Samsung TV app not working

Been having an issue the past month or so with the app attempting to reconnect while watching any channel on the Xfinity stream app on Samsung TV.  Also an issue fast forwarding through commercials in recorded programs.  Fast forwarding would actually jump backwards to the previous commercial block.  Both super annoying.  Today the app won't even load.  Tried all the troubleshooting steps including restarting the TV, the router, reinstalled the app, etc.  

I have an Amazon fire stick plugged into the Samsung TV.  Installed Xfinity stream app on the fire stick, guess what?  It works fine...  Also works on my iPad. 

So this is a problem with the Xfinity stream app for the Samsung TV app, period.  Any idea when there will be a fix for the Samsung TV Xfinity stream app?
