Hi everyone, My app has been rejected twice under Guideline 2.1(b) - App Completeness because the reviewer says the In-App Purchase does not trigger a purchase flow when tapping the purchase button. However, I have tested it on a physical iPhone (iOS 18.6.2) and the StoreKit purchase dialog appears and completes successfully. I have confirmed: Paid Apps Agreement is active In-App Purchase product (non-consumable) is configured correctly Sandbox test account works fine Purchase flow works on physical device with screen recording as proof The reviewer tested on iPad Air 11-inch (M3) with iPadOS 26.4. My app uses Flutter with the in_app_purchase package (v3.2.0). The purchase implementation: Calls InAppPurchase.instance.isAvailable() Queries product details with queryProductDetails() Calls buyNonConsumable() when user taps purchase button I found and fixed a potential null reference issue in the purchase completer that could cause the purchase to fail silently, but I'm not sure if this was the exact cause since I cannot reproduce the issue. Has anyone experienced a similar situation where IAP works on device but fails during App Review? Any suggestions on what might be different in the review environment? Thank you.
