Xfinity app is HORRIBLE

Hello, am I the only one that has nothing but trouble with Xfinity app trying to watch anything on the app!  Constant buffering (I pay for top Xfinity internet also) typically I get one day to use but never two without having to reset the Apple TV.  No other apps buffer or lock up or just don’t load any data 50% of the time.  Largest waste of $350 a month. If I could I would switch to YouTube TV today!
