I have my app configured all fine in revenuecat and AppStore Connect. Create a paywall in revenuecat. Create a StoreKit file and its certificate then upload “cer” file to revenueCat… All works perfect both simulator and real device associated with Xcode, I can simulate subscription and it is logged in sandbox transaction history in revenuecat dashboard.
The problem is when I upload a beta version to testFlight and beta testers download the app to test it. All of them have sandbox account added in their devices… same problem for all… a popup alert like I attached… I tried deleting StoreKit file and certificate from project and revenuecat web, but it doesn't work any way… the issue is still the same… any help? Anything I’m doing in a wrong way? :(
