Dish Anywhere works great on my iPhone, MacBook Pro and Windows 10 computer, however, on my Fire TV 4K Ultra connected to my LG TV, when I start watching either a live Dish channel or the DVR, it works fine for few minutes, only to suddenly go to a black, silent screen. On another forum, multiple posters reported the same problem, saying this error started in December, when the Dish Anywhere app was last updated. Do you guys know any more about this problem?
