This app is useless.
 When you try to watch a movie or anything on a phone or tablet, in my case, half the screen is the movie info and the top half is whatever you are watching with NO full screen or casting available. And I am trying to watch "in home" not somewhere else, not that it should matter.    Not only that  I cannot even watch from my windows pc either, it studders and is just    UNWATCHABLE!! The only way to watch anything is through the actual network app such as  HBO, In turn, this does not give a whole lot of options. If networks can create apps that work why can't Xfinity? There is no excuse for this.
          If I could I would change cable companies I  would. Comcast has gone down hill ever since the digital change over yet our bill keeps going up. Whats new? As far as being able to navigate faster, I could care less. It's like watching a TV show with the annoying channels icon at the bottom corner, only worse because it takes up half the screen ! Do these people         (Xfinity) who create these apps even test them out ?  I give the one start but not really, it should be a big fat 0!, ..............way to go Comcast.
