Update: Chromecast functionality was working, but with this latest app version, it crashes in videos and disconnects your casting sessions all the time now. Frustrating. The new update destroys Chromecast functionality. If you regularly use a Chromecast and cast from your phone, do not update. The app crashes every time you try to cast something. Nobody asked to have the YouTube app on the Chromecast have a full GUI, let alone implement that and then break normal cast functionality....
