Further to the Qobuz playlist issue, two of my 13 playlists just won’t play any track, stopping after ‘Loading playlist’. The other playlists play tracks fine.
I’ve tracked down the playlists bug - if a track is no longer available (shows grey in the Qobuz app) then the playlist won’t play any track. By deleting the grey tracks, the playlist will play any track again.
This is new behaviour, it did not happen with 2.799.
