I have been trying to use jellyfin locally but subtitles have issues some times depending on the show or format. Also recently my wife watched 2 episodes more than me so we needed to go back 2 episodes and only way to do that from the Up Next or Resume screens was to start a new search of the show and click into the season and then find the episode. I get supporting open source but for my jellyfin only has 70% of the features I use weekly on Plex. Definitely supporting it and trying to use it but it’s not feature parity for me
