Xfinity Stream on Firestick/firetv

A week or so ago we started seeing the ‘failure to upgrade please exit and restart’. Only on the stream app while using a firestick.  We have tried:

uninstall8ng the Stream App

resetting the stick to factory settings and reinstalling the app

At that point we thought our sticks were just too old for the app and we replaced the tv with a new fire tv. Only to have it still happening.  I came here for solutions and found it’s not our tv but a big issue with the app.  It’s frustrating because sometimes when I exit and restart stream it works. Others it gets stuck on the 3 flashing dots.

we can stream on our iPads fine
