U-verse app does not accept my u-verse login
I just installed the u-verse app on my wifi only iPad2 running iOS 8.1.2.
I'm using the same login username and password that I use to login to my account on the U-verse web site, but I get the message: "invalid U-verse Member ID or password. If you created an AT&T Access ID, enter your U-verse Member ID with Access ID password."
"forgot password" was successful in allowing me to reset the password, so it's finding the account.
Why won't the app accept my U-verse login?
