App Review cannot complete auto-renewable subscription purchase (Guideline 2.1) although sandbox & TestFlight work

Hello,

I’m experiencing repeated rejections related to Guideline 2.1 – App Completeness for an iOS app using auto-renewable subscriptions, and I’m struggling to understand what is missing, as the purchase flow works correctly in sandbox and TestFlight.

App setup:

  • iOS app built with React Native (Expo + react-native-iap)
  • Auto-renewable subscriptions: • Monthly: €4.99 • Yearly: €39.99
  • Paid Apps Agreement accepted
  • Subscriptions configured and active in App Store Connect
  • Privacy Policy and Apple Standard EULA included: • Visible inside the app on the subscription screen • Added in App Store metadata

What App Review reports: App Review states they are unable to buy the in-app purchase, resulting in a rejection under Guideline 2.1 (App Completeness).

What works correctly:

  • getSubscriptions() returns valid products in sandbox
  • Subscription titles, prices, and durations are displayed in the app UI
  • requestSubscription() is triggered when tapping the subscribe button
  • Apple purchase sheet appears and completes successfully in: • Sandbox testing • TestFlight (external testers)

What I’ve verified:

  • No conditional logic blocks purchases in review builds
  • Purchase button always calls requestSubscription
  • purchaseUpdatedListener and purchaseErrorListener are correctly registered
  • No hardcoded prices; prices come from StoreKit
  • Same behavior on iPhone and iPad

Question: Is there any known limitation or requirement in the App Review environment for auto-renewable subscriptions that differs from sandbox/TestFlight when using a custom subscription UI (not SubscriptionStoreView)?

If App Review requires a specific implementation detail (StoreKit 2, SubscriptionStoreView, or something else), I would really appreciate clarification, as this is not explicitly stated in the rejection.

Thank you for your help.

Did you check for unfinished transactions? In certain conditions, e.g. network issues, there might be unfinished transactions which will block purchasing the same subscription product.

App Review states they are unable to buy the in-app purchase

Have you asked what they mean by 'unable to make a subscription purchase'? It could mean that

  • the purchase sheet doesn't appear
  • they don't see a button leading to the purchase sheet
  • they don't see a list of products
  • they tap something that is not even a button or something without a tap gesture

I would make sure that I were on the same turf as theirs.
