Getting error message: Upgrade failure. Please restart the application

Receiving this message when launching the Xfinity Stream App on all of my TVs.   I have a mix of Samsung and LG TVs and am using the Firestick 4k+ for streaming.  If I exit the error and launch again it will work, but the error returns next time I turn on the TV and launch.    I have cleared data and cache from the app but still get the error.

It would appear the version of the Xfinity App you have is downlevel.  The most recent version is 8.15.1.3747. Xfinity just pushed that update out 2 days ago when everyone started posting about this problem, me included.

Now that they updated the App you will need to get your devices updated with that version.  Xfinity can’t do that for you.  If you don’t know how to update the app on your device(s) the best thing to do would be to uninstall the app on your device, go to the Amazon App Store and download the Xfinity App again and that should be the latest version.  Hope that helps.

No assistance required and thank you for removing the very vulgar comments from one of the Users I tried to help.  I hope that individual was banned from the forum.  There no place here for that kind of nasty vulgarity towards other Users.
