Happening since morning, I got rid of Gapps on phone (for privacy concerns) and can't use K-9 Mail anymore, guess I'll have to resort to mobile browsers for email access.
> I'm not sure if Google allows using phone notifications first (another 2fa method) and then switching to TOTP...
How is your experience so far with inboxing while using Mail In A Box?
The setting is also gone for me!
