Dear madam and sir,
iTunes playlists (iTunes version 18.104.22.168) are imported by TwonkyServer (I see sometimes running the itunes-import process in task manager at startup), but all playlists from iTunes are empty in TwonkyMANAGER or on my devices, to which TwonkyServer streams media content.
In iTunes playlists are not empty, also playlist files .m3u have titles included.
Hope you have a solution. I use TwonkyManager 3.0.4 (58) and TwonkyServer 7.0.11.
