PS
The Qobuz web interface and Qobuz app are more robust than the Lumin app (used on a dedicated iPad).
They all work but I think the SQ is best when using the Lumin app.
If using the native Qobuz playlists, listening to albums, or Qobuz playlists the Lumin app is no problem.
However, adjusting playlists works using the Qobuz native app or web interface. That’s a PIA as playing/listening is done with the Lumin app. It’s a lot of back and forth between apps.
