Same problem here, but I´m using Windows on a PC. I even tried making a new account but got the same message when attempting to log in.

Getting this issue when using the Android app on my Chromebook (Acer Spin 713).

WTH?!?!?!

(Still works just fine on my Android smartphone and on my Windows computer, though.)

All users are affected but this issue on all platforms. However, you can manually update on Windows. Ok Android, you cannot manually update to 2021.7.0 from 2021.5.61. When trying to login it fails to authenticate, regardless of the network connection we use.
