I have my iTunes library and library files on a Synology NAS. I have configured sharing to use SMB instead of AFP, but when I add the music folder, Roon only imports my music, no playlists. Is there a way to add iTunes playlists as well?
Not a solution but tip
Start here to export playlists.

Search here or on the internet to what file formats Roon accepts.
OR go to Soundliz.com and import your iTunes Playlist there and import it to a Tidal Account (Tidal Account Required). Roon does sync with Tidal playlists.
