Sync Playlist on webdav media server

Hi everyone, I use Symphonium on two devices with a WebDAV media server.

I can’t sync the playlists properly.

On the second device, I can see the playlists and track list, but I can’t play them: ‘Track not found’ error.

I read that it’s possible to import m3u files with the correct paths, but I thought Symphonium didn’t export m3u files. Is that right?

Is there a solution? Thanks.
