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?
I use Jellyfin server with the Infuse app and it works flawlessly.
ETA: I don’t love Jellyfin for music. I use Navidrome for iOS music and Lyrion for home/multiroom music.
