My iPad mail account suddenly can't recognize my password
Have att.net email account. ATT/Yahoo have recently introduced a new email system and now when I try to access mail using my iPad, a message tells me either my ID or password is invalid. Spent 3 hours on phone with ATT and they sent me in circles. Has anyone else had this iPad Mail service problem and how did you resolve it?
Many thanks.
iPad, iOS 5.1.1
