Absolutely useless!! I haven't been able to connect to my Samsung TV in MONTHS!! I've tried uninstalling, reinstalling, everything that has been suggested to others, and nothing. This app has shown my TV as offline for months and it's connected to the same network, etc. Samsung, the copy/paste apology asking for people to reinstall and also email you has clearly not been effective. The app does not work for many people, so please fix it!! Very frustrating.
