Xfinity Stream Apps not working on ANY of my TVs

We have used the xfinity stream app for a few years with no issues.  Last week it started acting up.  I could get the app to load and see the guide and all my recorded shows, but if I tried to play anything (live TV or a recorded show) I get a message that says unable to load.  Please try again. 

This issue is happening on ALL of my TVs. I have Uninstalled the app and reinstalled it.  I have unplugged my TV, I have deleted all of my saved shows.  I dont know what else to do.  

This is my exact message....Attempting to resume...weve run into a problem while streaming. Please wait while we try again. Then I get this video cannot be played.  Weve run into a problem while streaming.  (Error: TVAPP-00281)

Ive called xfinity and they couldn't help me.
