I see. The multi user support in Jellyfin is arguably one of its strengths so that’s a shame. Don’t have a good recommendation in that case.

Adult or not, Android/Google tv lacks good media centers or video players. Jellyfin, Kodi, Nova or VLC are basically your options and they are all crap in their own way. If you don’t want to watch something on Netflix, HBO etc. It’s really a bummer.
