No Live TV on Apple TV



I recently installed an HD Home Run Quattro with over the air tv and installed Plex Media Server on my 2010 Mac Pro but can't get Live TV to show up on Plex's Apple TV app. I can record and play back the show find but I don't get the option to play live tv and when I go into the program guide and select a show to watch now nothing happens. I do have Plex Pass. Is there something I an doing wrong? I have the latest 4k Apple TV.


Does anyone have an help to offer? Still nothing works... when I try to watch TV nothing happens when I click on the icon to watch the show.
