Hello.. I don't believe this information is correct... Method 1: I just spent about 2 hours with a Samsung support representative and then with a YouTubeTV support representative... At the conclusion of my YouTubeTV support session, the YouTubeTV support representative admitted YouTubeTV doesn't support the Samsung "Autorun last app" feature... Method 2: Moving YouTubeTV to the "first position" (after the immovable Smart Hub App) in the app tray doesn't cause it to be the "default" app... No matter what I do (including removing the "Samsung TV Plus" application), the YouTubeTV application is not defaulted... I will be dropping YouTubeTV until they smoothly integrate to the Samsung TV world with support for the "Autorun last app" feature...
