The Plex app on my TiVo Roamio seems to not work. It will let me see the menu, but not go any further, no actual playing. I have a Bolt in another room, and no problem there. And multiple Firesticks, all work fine. Just the Plex app on Roamio. Is there a way to delete and install a single app on...

i am totally lost with setting up plex. does anyone have a simple step 1,2,3 to set this up? so far, i can see on computer but my tivo seems not to be connecting to server (my computer?). thanks
