Sign in Issue with Iphone 12

I’m having trouble signing into my T-Mobile account in the app on my iPhone 12.  The Email address goes in ok but when I try to put in my password it doesn’t let me finish typing the whole password.  The boxes seemed to be overlaid a bit so I’m not sure how to get this fixed.  I’ve uninstalled and reinstalled the app and it still has the same looking screen. TIA.
