Tmobile Tuesday App

I tried to use my Tmobile app to redeem a reward for being a nurse. The  page to enter my name and demographic data was impossible to use on my phone. I even tried to use the desktop version to enter my info but was unable to enter the info in the boxes. The page size kept altering and when I zoomed back the cursor was immobile. After multiple attempts I went to my laptop, but of course I don't have access to the app. I can't even email customer support. I was very disappointed that I was unable to redeem the reward for being a nurse. It looked like a nice benefit.
