Hi there! Whenever I try to add a new Offer Code for my app's subscription, I get an unknown error. When I get to the last step of the "Create Offer for Codes" flow, I get an error that error reads "An error has occurred. Try again later." I have been getting this same error for over a week now, so any help figuring out how to add new offer codes would be greatly appreciated!

After the release of StoreKit 2.0, the in-app purchase failure rate increased by 63.19%, with the majority of errors being StoreKitError.unknown. When encountering this error, many users repeatedly attempt to make a purchase, but the outcome remains unchanged, resulting in the same unknown error.
In some cases, users who wait approximately 2 minutes before retrying the purchase may either succeed or encounter the following error:
“StoreKit.StoreKitError.systemError(Error Domain=NSCocoaErrorDomain Code=4097 "connection to service named com.apple.storekitd”)”.
This issue has directly impacted our app's purchasing flow.
Because our app only displays the promotional purchase offer once, these issues have significantly reduced the number of users successfully completing the offer. As a result, the conversion rate for this promotion has dropped well below expectations, negatively impacting our business metrics.
If an app on the App Store still uses StoreKit 1 (a.k.a. the Original StoreKit) to handle In-App Purchases, would IAPs work for users who download such app on iOS 26.2?
Would the app allow the users to purchase an IAP via StoreKit 1 or would it be impossible to buy the IAP on iOS 26?
The iOS Documentation says that SKPaymentQueue (which is a part of StoreKit 1) is "Deprecated" and "No longer supported.", with the support being for iOS 3.0–18.0.
Does this mean that apps using StoreKit 1 won't be able to make IAP purchases when running on iOS 26?
The app review prompt on iOS/iPadOS 26.1 has the "Not Now" button greyed out:
On iOS/iPadOS 26.0, this was working:
Before filing a radar, is there anything I'm missing? The only way to dismiss it is to tap a star rating and then a Cancel button appears which lets you dismiss it without reviewing.

I'm using code similar to the following to conditionally show the SubscriptionStoreView and the .storeButton(.visible, for: .restorePurchases) modifier is used to allow the user to restore an existing subscription.
How can I listen for events that would allow me to close this view once the subscription is restored?
The .onInAppPurchaseCompletion closure does not handle this and it also appears that listening for results in Transaction.currentEntitlements also doesn't handle the fact that a subscription is restored.
Any guidance on how to determine if the subscription has been restored would be greatly appreciated.
Finally, how can this be tested effectively in both TestFlight and in Xcode with the simulator.
if subscriptionManager.subscription == .none {
SubscriptionStoreView(groupID: "1234567") {
SubscriptionMarketingView(transparency: false)
.containerBackground(for: .subscriptionStoreFullHeight) {
GradientBackground()
}
}
.backgroundStyle(.clear)
.storeButton(.visible, for: .restorePurchases)
.storeButton(.visible, for: .redeemCode)
.onInAppPurchaseCompletion { product, result in
Task {
await subscriptionManager.entitlements()
}
}
}
Hi everyone,
I’m implementing subscriptions using StoreKit v2, and I’ve noticed a behavior change starting with iOS 26.1.
I’d like to ask if anyone else has experienced the same issue.
■ Issue
Immediately after purchasing a new subscription,
the value of auto_renew_status (or autoRenewStatus) returned in the receipt is 0 (auto-renew OFF).
This issue occurs on iOS 26.1.
On iOS 26.0 and earlier, the same parameter returned 1 (auto-renew ON) right after purchase.
Sometimes, after executing a “restore” operation, the value changes to 1 later.
Since we’ve been using this parameter to determine whether a user’s subscription is active or not,
the current behavior is causing some difficulties on our end.
■ Questions
Has anyone else observed this issue (where autoRenewStatus is 0 immediately after purchase on iOS 26.1 or later)?
How are you handling or working around this behavior in your implementation?
If autoRenewStatus is unreliable, we’re considering determining the subscription state based on receipt fields instead.
Would this approach be reasonable?
"status" is 1 (indicates active subscription)
"expire_time" is in the future
"deleted_at" is null
If anyone has encountered the same behavior or knows of any Apple-recommended implementation approach,
I’d really appreciate your insights.
Thank you! 🙏
Hi everyone,
I’m facing an issue where StoreKit is returning 0 products from the App Store, even though my auto-renewable subscriptions are approved in App Store Connect.
When calling queryProductDetails using Flutter’s in_app_purchase package (which uses StoreKit under the hood), StoreKit reports success but returns an empty list.
The logs show the following error:
IAPError(code: storekit_no_response, source: app_store, message: "StoreKit: Failed to get response from platform.")
InAppPurchase.isAvailable() returns true, but no product details are received.
Already verified:
• Subscriptions are approved in App Store Connect
• Product identifiers in the app match those in App Store Connect exactly
• In-App Purchase capability is enabled in Xcode
• Paid Applications Agreement, banking, and tax details are active and complete
• Using the latest version of the Flutter in_app_purchase package
StoreKit should normally return the list of available products in the production environment, but it consistently returns an empty array along with the “storekit_no_response” error.
Has anyone else encountered this issue or found any potential causes for StoreKit failing to return products in the production environment? Any insights would be greatly appreciated.
Thank you.

On this page:
https://developer.apple.com/documentation/storekit/testing-age-assurance-in-sandbox
It says:
Start with a Sandbox account.
What is a Sandbox account and how does one set one up?
Just it just simply mean an Apple account id used for testing, or something else?
I've been trying to make my app available on the App Store for a month now, but I can't because the signatures I created don't appear in the sandbox app. I did all the configuration in the store and in the app. I tested the same code in another app with signatures and it was loaded, but the signature for that specific app doesn't appear. I've tried contacting Apple support, but they can't help me. It almost seems like it's on purpose. I'm treated like crap and they don't even give me an explanation about what's happening.
Can anyone help me?
I'm using the iOS simulator with a StoreKit configuration file. I can see that there have been transactions while the app has been closed, but my StoreKit 2 listener is never called with those updates to be able to finish them When I open my app from a cold start.
I've added a listener on application(_:didFinishLaunching:launchOptions:) like this:
func startObservingTransactions() {
task = Task(priority: .background) {
for await result in Transaction.updates {
if case .verified(let transaction) = result {
await transaction.finish()
}
}
}
}
But the Transaction.updates loop never gets called (have added breakpoints to check). It's only ever called when a purchase is made, or subsequent transaction renewals when the app is open. Only then it will get the previously unfinished transactions.
Steps to reproduce:
Create an app with a StoreKit config file (with sped up transactions) to purchase an item
Make a purchase then quit the app
Wait for a bit for more transactions to be made while the app is closed.
Open the app from a cold start and none of the transactions will be finished by the listener in your app. Cancel the subscription via the transaction manager.
Close and open the app from a cold start. The first transaction will be finished by the listener but none of the others will be.
In Apple's docs it says
If your app has unfinished transactions, the listener receives them immediately after the app launches
Why is this not the case?
I'm working on a watchOS app that has an iOS counterpart. There will be a subscription required to unlock functionality and I would like the user to be able to make the purchase on either the iPhone or the watch and have both apps unlock.
The first link below says that StoreKit 2's Transaction.currentEntitlements will not work in this case like it does with extensions. The second link says it might work but doesn't in the sandbox.
What is the best way to make this work? Will it just work in the App Store? Should I use WCSession to send the purchase information from one platform to the other and store it in the keychain? Something else?
Via https://www.revenuecat.com/blog/engineering/ios-in-app-subscription-tutorial-with-storekit-2-and-swift/
"Transaction.currentEntitlements can be used in extensions the same way it was used in the previous steps. This works for extensions like Widgets and Intents. However, an iOS app with a companion watchOS app will not work even though Transaction.currentEntitlements can be executed in it. A companion watch app does not stay updated with the same transaction history as its iOS app because they are separate platforms."
Via https://developer.apple.com/forums/thread/739963
"In TestFlight I was able to confirm that the Watch app and IOS app share in-app purchases. It seems the problems confirming this with Storekit and Sandbox are limits of the testing environments."
Hi all,
I am adding the following StoreKit 2 code to my app, and I don't see anything in Apple's documentation that explains the unverified case. When is that case exercised? Is it when someone has tampered with the app receipt? Or is it for more mundane things like poor network connectivity?
// Apple's docstring on `shared` states:
// If your app fails to get an AppTransaction by accessing the shared property, see refresh().
// Source: https://developer.apple.com/documentation/storekit/apptransaction/shared
var appTransaction: VerificationResult<AppTransaction>?
do {
appTransaction = try await AppTransaction.shared
} catch {
appTransaction = try? await AppTransaction.refresh()
}
guard let appTransaction = appTransaction else {
AppLogger.error("Couldn't get the app store transaction")
return false
}
switch appTransaction {
case .unverified(appTransaction, verificationError):
// For what reasons should I expect this branch to be entered in production?
return await inspectAppTransaction(appTransaction, verifiedByApple: false)
case .verified(let appTransaction):
return await inspectAppTransaction(appTransaction, verifiedByApple: true)
}
Thank you,
Lou
Hi,
I am building a new app in the App Store - the app is not live yet.
I have setup an annual subscription product in AppStore Connect. Our problem is that we are unable to retrieve the product from our app - we've made sure that there are no missing metadata (e.g. price, availability).
Has anyone encountered before? Appreciate any help provided.
Thanks
I am using the public url https://api.storekit-sandbox.itunes.apple.com/inApps/v1/notifications/jwsPublicKeys to get the jwks keys to verify the signed payload for store kit payments. I am checking Apple server notifications.

// Apple JWK set (cached by jose)
const appleJWKS = createRemoteJWKSet(new URL(APPLE_JWKS_URL));
const jwks = await appleJWKS();
logger.debug("Apple JWKS Keys: %O", jwks); // Log the keys
if (!signedPayload) {
// return res.status(400).json({ error: "Missing signedPayload" });
}
// Step 1: Verify JWS (signature + payload) using Apple's JWKS
const { payload, protectedHeader } = await jwtVerify(

Hello,
Is anyone else seeing Purchase.PurchaseResult.UserCancelled, despite a successful transaction?
I had a user notify me today that he:
Attempted a purchase
Entered payment credentials
Was asked to opt in to email subscription notifications
Opted In
Was shown my app's "User Canceled Purchase" UI
Attempted to repurchase
Was alerted that he was "Already Subscribed"
I have adjusted my code to check Transaction.currentEntitlements on receiving a .userCancelled result, to avoid this in the future. Is this logically sound?
Here is my code - please let me know if you see any issues:
func purchase(product: Product, userId: String) async throws -> StoreKit.Transaction {
let purchaseUUID = UUID()
let options: Set<Product.PurchaseOption> = [.appAccountToken(purchaseUUID)]
let result = try await product.purchase(options: options)
switch result {
case .success(let verification):
guard case .verified(let tx) = verification else {
throw PurchaseError.verificationFailed // Show Error UI
}
return try await processVerified(tx)
case .userCancelled:
for await result in Transaction.currentEntitlements {
if case .verified(let tx) = result, tx.productID == product.id, tx.revocationDate == nil {
return try await processVerified(tx)
}
}
throw PurchaseError.cancelled // Show User Cancelled UI
case .pending:
throw PurchaseError.pending // Show Pending UI
@unknown default:
throw PurchaseError.unknown // Show Error UI
}
}
@MainActor
func processVerified(_ transaction: StoreKit.Transaction) async throws -> StoreKit.Transaction {
let id = String(transaction.id)
if await transactionCache.contains(id) {
await transaction.finish()
return transaction // Show Success UI
}
let (ok, error) = await notifyServer(transaction)
guard ok else {
throw error ?? PurchaseError.serverFailure(nil) // Show Error UI
}
await transaction.finish()
await transactionCache.insert(id)
return transaction // Show Success UI
}
The only place the "User Cancelled Purchase" UI is displayed on my app is after the one instance of "throw PurchaseError.cancelled" above.
This happened in Production, but I have also seen userCancelled happen unexpectedly in Sandbox.
Thank you for your time and help.
We’re testing SKAN postbacks via AdAttributionKit but aren’t receiving any requests on our server even after generating development impressions and triggering a postback.
Setup:
Domain: https://linkrunner-skan.com
Configured in Info.plist as:
<key>NSAdvertisingAttributionReportEndpoint</key>
<string>https://linkrunner-skan.com</string>
<key>AttributionCopyEndpoint</key>
<string>https://linkrunner-skan.com</string>
Apple automatically appends the .well-known paths:
/.well-known/private-click-measurement/report-attribution/
/.well-known/skadnetwork/report-attribution/
ATS diagnostics for the domain: PASS for all tests (TLS 1.0–1.3, PFS disabled, arbitrary loads allowed, etc.)
Both .well-known paths are publicly accessible and return 200 OK
Testing Flow:
Enabled Developer → AdAttributionKit Developer Mode on iOS (15+)
Followed Apple’s official guide: Testing AdAttributionKit with Developer Mode
Generated test impression using:
createAdAttributionKitDevelopmentImpression implemented in SKANManager.swift
Called Postback.updateConversionValue with lockPostback: true
Created Development Postback from Developer Settings
Waited 30+ minutes while intercepting server requests (proxy + backend logs)
What We’ve Tried So Far:
Confirmed ATS compliance with nscurl --ats-diagnostics (all PASS)
Verified .well-known paths are accessible publicly without redirects
Tested endpoints manually with a POST request – server responds 200 OK
Confirmed Info.plist entries exactly match Apple’s required keys
Double-checked iOS device is running iOS 15+ with Developer Mode enabled
Repeated test flow multiple times with fresh impressions and postbacks
Waited up to 1 hour for postback (in case of delays)
Issue:
No POST requests are being received from Apple to either .well-known endpoint, even though the setup appears correct and ATS tests pass.
References Used:
Configuring an Advertised App
Generating JWS Impressions
Question:
Has anyone faced a similar issue where AdAttributionKit Development Postbacks are not firing despite correct Info.plist setup, ATS compliance, and reachable .well-known endpoints?
Any insight into possible missing configuration steps or testing nuances would be greatly appreciated.
The majority of our sandbox calls to verifyReceipt end in an ETIMEDOUT error. This is making it very difficult to verify our purchase flow for our pending release. We have not yet migrated to StoreKit 2 and still rely on this API endpoint.
The Apple API status page reports no issues.
Is anyone else encountering this?
Over the past two days, we've observed an unusual spike in requests from some iOS users to our server endpoint responsible for verifying App Store purchase receipts.
After sampling and analyzing the data, we found that the cause is related to the behavior of StoreKit2.Transaction.updates. Specifically, when listening for transaction updates, the system returns a large number of historical transactions — some dating back as far as one year. These callbacks are interpreted as "new" transactions, which in turn trigger repeated calls to Apple’s receipt verification servers, leading to an abnormal surge in traffic and putting pressure on our backend services.
This behavior is ongoing and is something we've never encountered in our previous experience. It appears to be outside of expected behavior, and we suspect it may be due to some kind of abnormality or unintended usage scenario.
We would appreciate guidance on the following:
Is this a known behavior or issue with StoreKit2?
Are there specific device states or conditions that could cause the system to emit historical transactions in bulk?
Are there any recommended practices for mitigating or filtering such transaction floods?
We have attached logs for reference. Any help identifying the root cause or suggestions for investigation would be greatly appreciated.

I’m seeing an issue with subscriptions in TestFlight builds on iOS 26. Running from Xcode works as expected, and the App Store build looks fine. But when I install the same build via TestFlight, transaction.subscriptionStatus is nil.
The identical binary behaves correctly on an iOS 18 device.
Is this expected behavior on iOS 26 TestFlight, or am I missing something?
Thanks!
Dear Apple Technical Support Team,
We have encountered a potential issue related to transaction handling while using StoreKit v2, and would greatly appreciate your assistance in confirming the behavior or providing any relevant guidance.
Issue Description:
When calling Transaction.unfinished and listening to Transaction.updates on the client side, we noticed that some transactions—despite having already been processed and successfully completed with finish()—are being returned again upon the next app launch, which results in duplicate receipt uploads.
Current Handling Flow:
1. Upon app launch:
• Iterate over Transaction.unfinished to retrieve unfinished transactions;
• Simultaneously listen for transaction changes via Transaction.updates (e.g., renewals, refunds);
2. For each verified transaction, we immediately call await transaction.finish();
3. We then construct a transaction model, store it locally, and report it to our backend for receipt verification;
4. After the server successfully verifies the receipt, the client deletes the corresponding local record;
5. On every app launch, the client checks for any locally stored receipts that haven’t been uploaded, and re-uploads them if necessary.
Key Code Snippets:
private static func verifyReceipt(receiptResult: VerificationResult) -> Transaction? {
switch receiptResult {
case .unverified(_, _):
return nil
case .verified(let signedType):
return signedType
}
}
public static func handleUnfinishedTransactions(payConfig: YCStoreKitPayConfig, complete: ((YCStoreKitReceiptModel?) -> Void)?) {
Task.detached {
for await unfinishedResult in Transaction.unfinished {
let transaction = YCStoreKitV2Manager.verifyReceipt(receiptResult: unfinishedResult)
if let transaction {
await transaction.finish()
if transaction.revocationDate == nil {
let receipt = YCStoreKitV2Manager.createStoreKitReceiptModel(
transation: transaction,
jwsString: unfinishedResult.jwsRepresentation,
payConfig: payConfig,
isRenew: false
)
complete?(receipt)
}
}
}
}
}
private func observeTransactionUpdates() -> Task<Void, Never> {
return Task {
for await updateResult in Transaction.updates {
let transaction = YCStoreKitV2Manager.verifyReceipt(receiptResult: updateResult)
if let transaction {
await transaction.finish()
if transaction.revocationDate == nil {
let receipt = YCStoreKitV2Manager.createStoreKitReceiptModel(
transation: transaction,
jwsString: updateResult.jwsRepresentation,
payConfig: self.payConfig,
isRenew: false
)
self.callProgressChanged(.receiptPrepared, receiptModel: receipt, errorType: .none, error: nil)
}
}
}
}
}
Our Questions:
1. Is it possible for Transaction.unfinished or Transaction.updates to return transactions that have already been finished?
Specifically, if a transaction was successfully finished in a previous app launch, could it still be returned again during the next launch?
2. Are there any flaws in our current handling process?
Our current sequence is: finish() → construct model → local save → report to server → delete after verification. Could this order lead to timing issues where StoreKit considers a transaction unfinished?
3. If we need your assistance in investigating specific user transaction records or logs, what key information should we provide?
We greatly appreciate your support and look forward to your response to help us further optimize our transaction processing logic.
