Hi Remko,
Its not working for me. i might have to give up. I did some edits on a playlist this morning on my phone, made sure i was connected, run force sync, seemed all good. Only to find tonight on my computer that my deleted/ moved tracks are still there on edited playlist. Funny thing is that the edits i made sorting tracks onto other playlists have registered, but tracks haven't moved when i removed them from playlist from my phone. very frustrating.
