Hey @Thomas_Prossima1,
Thanks so much for letting us know right away of what you’re seeing.
The screen you’ve shared is actually New Releases for you, not Daily Mixes. It is expected for the albums under New Releases for you not to be in your library. These are albums newly released by Qobuz and featured under this section.
The Daily Mixes are lower on the same Home view. Also, the Daily Mixes do not necessarily contain music already in your library. Starting from an artist in your library, a playlist is generated with other artists as well. Please, find the quote below from our release notes:
Each playlist is themed on an artist from your listening history and includes 25 picks from artists you love and some you have yet to discover.
