Why does the T-mobile app take up so much space?

I have no idea what T-Mobile was tracking, but rolling back to an earlier Android version of the app cleared out all the user data and hasn't caused a problem since. Maybe T-Mobile was  taking snapshots or something to make restoring the phone easier. Whatever it was, it should have never been implemented this way.

It works!!!! Omg thank you Jesus!! T-Mobile really need to work on something with that.
