NEVER MIND: I had turrned off allow insecure apps in gmail by mistake. Android: Can't sync to Gmail - (command:*sensitive* response #3# authentication failed

Hello;

Suddenly, on both my phones (I am upgrading from a Pixel 3XL to a Pixel 6 Pro) when I try to sync to gmail I get a can’t authenticate error username or password incorrect.

However, if I use the Outlook app (yuck), it syncs fine. So, it is something with K-9 for Android.

I deleted the program, but no luck.

Thanks, in advance, for assistance.

Maybe this helps:
