Like I mentioned earlier, using the Search feature in the Qobuz app to search labels is pretty hit or miss. However, I just discovered somewhat of a work around to get Qobuz to display all albums from a particular label.
In the Qobuz app, select any album by the label you are looking for.
On the album page, select the 3 dots in the upper right corner.
Select “Album Credits”.
Then click on the label name. Qobuz will then list the albums available under that label.
This isn’t as convenient as using the Search function, but the results are much better.
