App is very dysfunctional on just about every one of my devices. Live tv wouldn't load for a while, resuming a show didn't work, casting didn't work. Example - started a movie in one room no problem. Moved to a different device = wouldn't load, finally acted like it was loading, played ads then went back to the main screen. Tried again, ads played fine, then back to the main screen. This happened repeatedly. This type of thing is the norm for this app. Come on, NBC. Do better
