The Jellyfin official app for Tizen TVs has been available through the Samsung store for several months now.

I was considering a Plex sub to make things easier to share my collection with family and friends who aren’t tech savvy enough to sideload stuff and the second that the Tizen app was approved, I closed the Plex chapter of my life forever.

There now is a real app dor samsung tizen and before that you could sideload one from github (though thats a different flavor of technical then a docker server)
