Stream app shows only Purchases

Hello,

When I start the Stream app on my TV, it goes directly to the Purchases screen, showing only purchased movies and Settings. There is no option for streaming or live TV. On my other devices, the app works properly.

My TCL Roku TV is in the compatible devices list and the software is updated. The app is the current version. I am connected via hard wire to the modem. All my other apps work fine.

I have tried talking to 4 different Xfinity reps and they were unable to help. I uninstalled and reauthorized the app many times & then factory reset the TV, too - the issue is not on my end. It appears my TV's Stream app doesn't recognize me as a current subscriber. Per google, I need help to "reprovision my streaming device entitlements." Can someone please help?
