thanks HG, that's what I suspected. I emailed Lumin and got no response. I will now email Qobuz. I like the music choices and the sound quality is terrific.
Lumin App-Qobuz Question
I can't figure out how to get albums I add to favorites to be configured alphabetically by artist instead of date I added. Thanks to any who respond. When using Tidal there was a little pictograph in the source bar you could tap and it would rearrange the albums from date added to alphabetical by artist. I can't find that using Qobuz with the Lumin app.
