I couldn’t connect.
Got frustrated and uninstalled/reinstalled (shouldn’t have to but W/E Blizz)
Tried logging in, kept ignoring my login attempt and sending me back to Touch To Start and error kept repeateing.
Important: I was trying to use my autofill to log in. So I manually typed it in.
It worked. BECAUSE. I have the authenticator hooked up and I think that was the issue. Because when I manually typed in the info the authentication message popped up. Now I’m in the game.
See if this helps.
