This is the behavior I am seeing too... so weird! I would think Apple would make it a high priority to "fix" their music app...12.3.1 fixed the problem but then it stopped working. I did a restart on my Mac and after changing a playlist everything synced and life was good for a while. Next day it was not working again and another restart fixed it. Strange behavior!
I have 12.3.1 on my MacBook and Apple Music still doesn't sync properly.Same problem here also. I installed the Mac 12.3.1 OS update and it worked after the restart but not after that. I have wasted so much time on this issue
I have 2 methods that seem to work a little bit, if I update any playlists on my MacBook then make a duplicate, then they will sync to my iPhone. or if I reboot my MacBook into safe mode, then they all automatically sync to my iPhone.I'm currently running with 12.3.1... when I first installed that update, this music issue was fixed... all worked as it is supposed to work... the next day, it stopped working again... when I reboot the computer, things work again (for that first day)... then it stops again... I have done this multiple times... everything works right after the reboot, then at some point (which makes NO sense) it just stops working again... until the next reboot...
the newest Monterey update I think fixed the issue, because it is working as it shouldNo, because it's a macOS issue.
yep fixed for me now!the newest Monterey update I think fixed the issue, because it is working as it should
