On my new 6s, Mail keeps telling me that my Gmail address does not "match" my account. And the Settings page for mail is shadowed out so I can't change any parameters there. I'm at my wits end. I've changed passwords about 4 times. After rejecting my password, when I go thru the "Next" windows to the end they tell me that my password is correct (until I try using it!!) There must be a ton of mail on the server that cannot get into the phone! I hope someone is expert enough to understand what's going on and steer me in the right direction.
