Hello @sam996 !
Thank you for sharing your concern through the Community Forums! Being unable to manage your account online can definitely be an inconvenience. I will be more than happy to help!
I also appreciate bigbiteme for bringing this to our attention. If you have already tried the basic troubleshooting steps and the problem persists, the best ways to report an issue with the app is by filing a technical case and escalate it for investigation.
Please send us a private message to @ATTMobilityCare with your full name, account number, phone number and a good time to contact you. This way I can gather detailed information to investigate what is causing this error and find the best resolution.
I look forward to get this issue resolve as soon as possible.
Enjoy the rest of the week!
