Here’s what I would do:

• Create jellyfin account for them with limited access
• Get android tv streaming stick, install jellyfin on it
• Install custom launcher and configure it to autolaunch jellyfin, and hide all other apps

Nice! Which sensor did you use for pollen?

Which bugs?

Skip intros and credits is available on Jellyfin.

I think the Plex UI is still better than Jellyfin, but I’ve gotten used to it.

Never used the smart collections when I was on plex, so can’t speak to that.
