Log on to U Verse app not working on Fire TV or iPad.

Can you login to the myAT&T app?   Should use the same credentials.  

Yes I could. The issue resolved itself later in the evening.

It's great to hear your app is working now, @BongoandKoko!

If you need assistance in the future, feel free to reach out!

Thank you for being the best part of AT&T!
