FYI you have to delete the song/album and re-download to get the Dolby Atmos version. I am slowly updating my ayu discography....
How can I get a Dolby Atmos version of a song that I already downloaded to my library?
To get a Dolby Atmos version of a song that you already downloaded from Apple Music, just delete the song and redownload it from the Apple Music catalog.
