Did anyone manage to go past the sign-in screen in MyAT&T app?
I figured the app has a very weird behavior where it immediately crashes if either of the DCL settings are set to 'allowed'. If all of them are restricted, then app manages to open but without the sign-in working (giving uh-oh error).
The only way I see it working is with Exploit Protection Compatibility Mode enabled. (I know that's just a bad app, just not sure whether it's worth it. I will restrict the background usage is there is no way around it)
