@Aaron_Lloyd as expected in that other post I can’t reproduce, added a .m3u at the root of a source with some files in it and it’s properly visible and imported in Symfonium.
Do you think you can give me an access on your server to those playlist so I try to figure out what’s going on?
Check if it’s an upstream issue with Jellyfin by creating a playlist via the web client with one track in it so that Jellyfin produces a playlist shortcut. Then check again with Symonium
That solved it. Had the same problem. Playlists over m3u files are displayed in jellyfin, also in finamp. But not in symfonium so far. After I created a playlist in jellyfin, as described here, they all became selectable in symfonium too. Good job.
Ah: So when you create a playlist directly in jellyfin, a playlist library is created there. If this is displayed on the home page, then the playlists are also accessible via symfonium. If I delete this playlist library (m3u files still remain in the music folder and are available under the music library and there playlists) they are no longer findable by symfonium.
