Hi there
Welcome to the AT&T Community Forums and thank you for posting your question. I’m sorry to hear you are unable to view your bill through the myAT&T App. This is not the experience we want anyone to have and I’ll be happy to help you get this resolved today!
For complete steps to getting the app working correctly based on what happens when you attempt to view your bill, please visit our Troubleshoot the myAT&T app page and select Smartphone / myAT&T app on the device drop down.
Please let me know if these steps work for you and have a great day!
Tim, Community Specialist
