Xfinity Stream Beta Closes to Home Screen Upon Launch

Hello,

I have a Roku connected to a TV and for almost a year, we have had no real issues with the app working.  Approximately a month ago I noticed an issue when I launch the app from the roku homescreen, the app launches, then closes and goes back to the roku home screen.

I have tried uninstalling the app - resetting roku - uninstalling app - resetting roku - installing app - resetting roku.

This happens on BOTH my roku devices, the only way to watch TV is to uninstall the app and re-install it, also have to go to xfinity.com/authorize (now a shortcut on my homescreen).....

Please help.

Thank you
