Roku stick with Xfinity streaming app shows no streaming content available, only items purchased

On Roku model 3941X2, software version 15.0

 

Opening the app shows a screen that at the top says , 'Purchases' on the left and on the right it has 'settings' followed by the time. Like I'm in a sub menu.

 

There's no streaming content available and no way to get to the main screen that shows when I use the app on other devices.
