Library
1200 local albums
Circa 8k albums 100k tracks from Qobuz
Problem: All Qobuz favourites disappeared from library 2 days ago in two stages. Some tracks still in play lists and will play. All favourites present on Qobuz. New favourites will add. Similar issue to the synchronisation issue experienced by many in June including me.
Matter raised with Qobuz who have apparently referred to you.
