Serviio not adding playlist [BUG]

Hello.

I think I've found a bug in Serviio.

In Serviio Pro version 2.4 (QNAP ARM 64-bit package), playlists added to the library appear in the log file as successfully indexed but do not show up in DLNA clients (e.g., Foobar2000, BubbleUPnP) unless the server is manually restarted.

Steps to Reproduce

Navigate to Library > Shared Folders in Serviio.
Untick the checkbox for "Keep library automatically updated".
Copy a folder containing audio files and an .m3u playlist to a designated audio shared folder.
Click Force Refresh in Serviio.
Observe the log entry indicating the playlist has been added:


  Code:

    "2024-11-29T19:35:52,338 INFO [PlaylistFileIndexer] Added playlist 'Some Music playlist!' to Library."


Check the DLNA client (e.g., Foobar2000, BubbleUPnP) for the playlist.

Expected Result

The playlist 'Some Music playlist!' should appear immediately in DLNA clients after being indexed.
Actual Result

The playlist does not appear under DLNA clients unless the Serviio server is restarted.

Workaround

Manually restarting the Serviio server resolves the issue:

Navigate to Status > Server Status.
Click Stop Server.
Click Start Server.
The playlist 'Some Music playlist!' now appears under "Audio" in DLNA clients and is playable.

Let me know if you need any more info.

On occasion when I edit a playlist the revised content does not appear unless I use the force refresh button under Shared Folders. I don't think I've had a problem with a new playlist not appearing, but I will say that all my playlists are in the PLS format, not M3U.
