Can't sync library on desktop version of Apple Music
After switching from Spotify to Apple Music and successfully syncing my library on the iOS app, I can't do the same on the desktop version.
I followed the tutorial: https://support.apple.com/en-sg/HT204926#turnon but it does not work for me. I do not get that option which is rather strange.
I would like to understand why I can't sync my library and what should I do to fix it. My macOS is the latest version.
Thanks.
