Help/Support Problem with game login using apple id

[Dyvcjkn 0 iPhone Xs Max 18.7.1]

Let me ask why the game can't log in to the apple id. For example, the game siege rumble that I'm playing, every time I want to log in with the apple id, it will show connecting, but I've waited 10 minutes and it still shows connecting. Why is that? I hope to get an answer.

Your certificate must support apple id signin which only available on paid apple developer account

Free sideloading for example Sideloadly/ Alstore/ Sidestore do not work or supported

To make Apple ID login and other entitlements work, you need to buy a personal Apple Developer certificate. Free sideload certificates from Sideloadly or AltStore only let the app run, but they don’t include the rights required for “Sign in with Apple.” With a paid personal certificate, the app gets proper entitlements and Apple ID login will function correctly.
