So I'm trying to login to T-Mobile app on my iPhone and its showing me some number that I have no idea what it is or where it came from. I tried rebooting the phone and still nothing. This seems like a security issue because I'm seeing someone elses phone number in my app when trying to login. I can no longer login to the app because I cannot get rid of the number that is showing up in the app!

That is super weird!! Can you try uninstalling the app from the phone and re-downloading it from the App store to see if that clears out the number?
