Mail App Says user name or password is incorrect
Happened on both iPads so not a hardware problem. We have 3 gmail accounts, no problem using gmail app or gmail web mail. Two days ago ipad Mail app would not access gmail accounts saying user name or password was incorrect. Finally fixed the problem by deleting accounts, uninstalling/reinstalling Mail app and adding back accounts. All worked fine until today and same problem came back. Have tried everything I can think of - changed google passwords, reset network connections, deleted accounts, uninstalled/reinstalled Mail app, added back accounts. When I add back the new account, Mail app verifies the email account but, after I add the incoming/outgoing server info, I get the message.
Any ideas?
