I have been able to log into and manage my account with my iPhone 6 using the myAT&T app until a few days ago. Now I get a white screen with the words "Technical Difficulties" in red letters, and then "We are having technical difficulties, Please try again after some time".
So I've been waiting for a few days, but this hasn't changed. I am able to log into with my home computer, but not with my iPhone or iPad. I cycled power in the iPhone, deleted and reinstalled the App but the behavior is still the same.
Is there really a problem on the ATT side, and I will just have to wait? If so can you estimate how much longer before this App works again?
