Fair enough, it works well enough on Xbox and I assumed the latter, but I guess not haha.

Android TV is garbage as a device though. Xbox is far more usable. Jellyfin being garbage on Xbox is the easiest thing to fix in the chain.

Xbox/ps5 + Plex. Turn it on, get loud beep, turns on TV for you, goes to input, designed for ease of use even for kids. Parental controls can limit what stuff they open (they are still going to see it though which may be a problem).

I’m sorry the jellyfin mouse only UI is far harder to use than a remote or controller in Plex.
