Before, I was able to Chromecast channels to my smart TV without any problems. Now, it keeps freezing and giving me error codes. It's definitely the app because I don't have any issues sending shows from other apps to my smart TV. Update: App constantly buffers which is driving me insane!! I can't get through a complete show or movie without it buffering a million times. It's starting to freeze within movies/shows again. Plus, Chromecast works when it wants to.
