Playlists disappeared on Mac
To fix a problem, Apple Support told me I would have to deauthorize and authorize my devices, which I did. Now all my playlists are not only gone from Apple Music on my Mac, there is no Playlist choice in Sidebar > Library. Once I chose File > New > Playlist, I could see where they should be, but they're all gone. I spent hours and hours creating those custom playlists! Is there any way to get them back?
Mac mini, macOS 10.15
