I am having constant issues with the IAP on my app. I have now, after several review rejections, created a brand new non-consumable in-app purchase product and updated the submitted build to use the new product identifier. We also updated the paywall so it no longer loops and instead shows fallback messaging plus manual retry/restore options when pricing is unavailable.
However, in TestFlight and sandbox testing, StoreKit is still not returning the product details, so no localized price is available to display. This suggests the in-app purchase is not being returned by Apple’s review/sandbox environment rather than a client-side UI issue.
Has anyone else had this issue and of so how did they resolve this?
