Hello @Amyemie!
I am sorry to hear you have been experiencing issues with viewing your bill via the app. This is definitely not the way it should be working, and I would be happy to assist.
Sometimes when the app will not pull up the account, the cache may need to be cleared. To find the steps to do this, please check our Device Support Center for your phone and tablet.
Once you reach the page, just select the make/model and then click Tutorials> Troubleshooting> App troubleshooting. After clearing the cache on the device, please restart it and try accessing the app again.
Another option to find out if the issue is with the account is by opening up the webpage login through the device’s browser. If you are able to view the billing information, then the concern is with the app.
A great way to solve this, and many other issues, is by visiting our Troubleshoot & Resolve Tool. Logging into your account when you reach the page will create a comprehensive and personalized troubleshooting experience. Please select the device, and then Device/software issues> Apps.
I hope this helps!
Fiona, AT&T Community Specialist
