Music.app doesn't show "Account" menu
Suddenly the Music app lost the Account menu and I cannot see the Apple music. I do see my own library. The strange thing is that the other "users" that I have on my iMac Music works fine. Only my user doesn't show the accounts. It's a late 27" 2019 iMac, under Big Sur.
Please help! I can't work without music. Thanks.
iMac 27″, macOS 11.0
