Hi everyone,
In the event that you added a track from an Album (and not the full album) to your library, and you navigate to that Album in your Library, only the added tracks from your Library will be displayed.
To see all tracks in the album, navigate to the “Versions” tab and click on the full album from the same source (Qobuz, TIDAL, or local content) as the content you saved. This will take you to the Browser page of the album (not the Library page of the album) where all tracks are listed.
Note that this will not function in Offline mode, as it requires a connection to non-downloaded content.
