Problems with iTunes playlists and added songs in itunes new folders

I use a NAS to store my itunes library - which is updating to mirror my iTunes library.

The issue is that Roon does not load playlist or new music that itunes adds to a subfolder in the iTunes library and Roon fails to find it.

I am sure that this is a common problem - please tell me how to get my new playlists and new music to be read by Roon.

Peter, is your iTunes Music Library.XML file also being imported, and do you have Import iTunes playlists enabled on your watched folder for music? Please see this link below on how to ensure both are working for you:
