so game center login stopped working normally, but thankfully you can just re-enter the setup after installing certificates to sign in. however, it will just randomly sign you out of game center after about 2 weeks of signing in. you will need to repeat the process again to sign back in, which can be frustrating because it resets some settings, deletes your icloud notes stored locally, and deletes email accounts from your device. does anyone have another trick to sign in to game center?
