I’m currently a Plex user and access it from Apple TV’s. I find this is a smooth and stable experience that everyone in the house enjoys and is comfortable. I also use PlexAmp on laptops, mobile and CarPlay.
I am interested in Jellyfin and am wondering if I can expect any hurdles or rough edges moving over?
It’s working pretty smoothly for me. I set it up a while ago, so if I encountered any problems I don’t remember them.
