I'm experiencing an issue where monthly and family monthly subscriptions fail immediately with "purchase cancelled" in TestFlight, while yearly and family yearly subscriptions work correctly. Setup: All 4 products in same subscription group All show "Ready to Submit" status Using react-native-iap with StoreKit 2 Testing in TestFlight sandbox The Problem: Yearly subscriptions work fine Monthly subscriptions fail immediately with E_USER_CANCELLED (no dialog appears, user didn't cancel) What I've verified: No active subscriptions (getAvailablePurchases() returns empty) No pending transactions Same subscription group for all products Product IDs match App Store Connect Code is identical for all products Error: E_USER_CANCELLED fires immediately when calling requestPurchase() for monthly products, but yearly products proceed normally. Questions: Why would monthly fail while yearly works (same group, same config)? Could this be sandbox state corruption for monthly products? Should I delete/recreate the monthly products? Any insights would be appreciated!
