iPhone 12 IOS 15.1 could not load Digital Life app. White screen after input username/password.

This problem is fixed with renew username/password.

Maybe AT&T hasn't updated the app for iOS 15.1. You might want to delete the app, power cycle the iPhone and then try to reload it again.

I would be utterly shocked to hear that the Digital Life App development team spent anytime testing and certifying for the latest iOS release.

It seems that there is no solution or promising on fixing this issue. Right?

@ATTDigitalLifeCS , the marked solution shows that the user was able to get in after "renewing" his username/password.
