Been with TMobile for well over 10+ years. No matter what they do, no matter how many updates they do to their app, it always freezes or stops working/crashes no matter what phone I have. I've had a couple of iPhones, a couple of LGs, and a Pixel throughout my tenure with TMobile. It also doesn't help when I'm looking around for something specific in the app and can longer find it because they change the layouts so often. Wonder why it's so difficult for them to have a fully functional app.
