We have had Xfinity only a few months & we're ready to go back to AT&T..This app has so many issues it takes up to 15-20mins just to load each time u turn on tv.. it pauses & freezes when u change channels & can take 10min sometimes just changing from one channel to next..box keeps shutting off..sound goes in & out & it sends u to 3rd party apps to watch just about everything then shuts the box down cause it does'nt have that app on xfinity & u may have to replace your box.
