Found out something new - please cut me some slack if I sound really dumb.
Yesterday, my partner tried to scan in to a shop and discovered she was logged out. Even though the email and password fields were populated her phone wouldn't log in - phone said "an error occurred trying to sign you in" Turns out that you need an internet connection for the google password thingy to work. I suppose everybody except me knows this, but the question is, why couldn't the error message say "turn on data, dork"?
