Hi all, currently using auto renewable subscriptions (monthly + yearly) using RevenueCat. App Review on iPhone 17 Pro Max and iPad Air 11" (M3) running iOS/iPadOS 26.3.1 reports that after attempting to purchase a subscription in sandbox, the subscription screen loads indefinitely / they can’t proceed (Guideline 2.1(b)).
I can reproduce successful purchases on physical devices via TestFlight using fresh sandbox tester accounts (along with 3 other internal users), and I’ve implemented post-purchase syncPurchases() + CustomerInfo refresh/backoff, restore fallback, and a dedicated “confirming purchase” screen to avoid the paywall blocking.
Has anyone seen review-environment sandbox sessions where purchase succeeds but entitlement/receipt validation never completes on certain devices/OS versions, and is there any recommended approach for making review more reliable?
Currently have another review pending and I attached a screen recording of everything working with a fresh sandbox account + physical device.
