can't sync 1 specific playlist
hi, i'm on ios 14.7.1 and macos 11.5.1.
I use the Music app to sync mp3s from my macbook to my iphone. works as expected with smart playlists as well as manual playlists.
there is 1 specific smart playlist that will not sync. it's a list of the 150 most recently added songs to the Music app.
when i check for it to sync in the finder window, it shows that it's copying songs over, but when i go to my phone, the playlist is empty with no songs.
i'm not getting any error messages. any ideas on what to do?
