Can't sign into Yahoo.com email. Redirects to ATT with error code
When I go to mail.yahoo.com to sign into my [email scrubbed] the page redirects to att.com and gives error code 652314
att help is a maze of unhelpful information that doesn't apply to this issue.
I cannot sign into my Yahoo mail in a browser at all anymore due to this error.
I cannot make changes to my account such as add a phone number to it so I can sign in that way.
I am not pleased.
