Apple Music won't sync in macOS Monterey

I have tried that several times and it still does not work? I have un-synced my music and re-started my computer several times but nothing ever seems to change. On my phone playlists will never update? Thanks.

Thanks for the help, hopefully they do resolve it because I haven't been able update the music on my phone for over 2 months now. As I said before even with un-syncing everything and re-starting my computer and then re-syncing nothing seems to solve the issue? I guess maybe I"ll just have to wait and see if they can resolve it on their end? thanks again.

So I dowloaded and installed the new 12.3 update, then went to Library and updated my iCloud library. But still nothing changed, it didn't update any music on my phone? So I un-synced my music library again in Apple Music and restarted my computer thinking this would help. But now when I try to re-sync my Apple Music library I keep getting an error that says Genius Can't be updated the network connection was lost? But there is nothing wrong with my network and now I can't even sync my library and this has gone on since yesterday? I'm at a total loss now?

Sorry the delayed response. So nothing you suggested seem to resolve the issue so I decided to remove Monterey and re-install Big Sur. Then I upgraded to Monterey again which seemed to solve the issue, everything was working good and my Apple Music was updating on my phone when I created a playlist on my computer. I was ecstatic I thought the issue was solved. But then about a week after I upgraded I ran into another issue, all the playlists I had created after I originally installed Monterey started reverting back to the original playlist. As an example if the original playlist had 10 songs and say I added 10 more songs and rearranged and edited the playlist, everything would be fine for a few hours. But then when I would go back to that playlist it would revert to the original 10 song playlist? All the songs I had added disappeared and songs that were rearranged reverted back to the original playlist which was created right after I installed Monterey for the first time. So again I was completely frustrated I thought maybe the playlists were possibly compromised so I copied and pasted all the songs from one playlist and created a new playlist with a new title thinking this might solve the issue? It did for a day or two where when I edited them on my computer they showed up on my phone as they should. I thought again maybe that was the problem so I deleted the old playlists and continued using and editing the new ones which I had created with new titles. Then even thoughs playlists stopped updating to my phone..... and then The old playlists which I had deleted in Apple Music kept reappearing, each day I would delete them and the next day they would show up in my Apple Music? Honestly Im sorry I feel like I'm rambling, I know this is a "first word problem" but I've never been so frustrated with Apple before. I've pretty much stopped making playlists because I know any new playlist I create or edit is just going to revert back eliminating all the work I had? Maybe I am the only one with this issue, I feel like I should have stuck with Big Sur.

Thanks.
