I have app in production that using anonymous user ids only, no login system. I installed my app to iPhone and get my App User Id from there to add entitlement to myself to test. After I added it to my user id and manual restore in the app - it works, entitlement appear.
Then I uninstall my app and install it again to test that RevenueCat will create user id alias for the same device (or Apple id) and that I can restore that entitlement again, but no luck, new app user id didn’t aliases to the first one - it’s just new one without any entitlements.
By the way it seems to work when I use TestFlight - after reinstall it aliases and restores my entitlement.
Is that bug or something? I thought that it can be the issue with real purchases.
