Finally fixed the Samsung/Xfinity stream issue!!

I was able to go to the Samsung website and follow the link for support for my model TV (Model QN75Q80AAFXXA) and downloaded the current firmware (22100) and all issues with streaming on the Xfinity app have been resolved... YOU'RE WELCOME XFINITY!!
