Apple Music Sync Error: 'Genius results can’t be updated right now. The network connection was lost.'

No... It's nothing you did.. it's not related to an upgrade I haven't upgraded and still have the issue. People on Windows have the same issue. It's a backend issue on Apple's side. Don't waste your time downgrading or reinstalling anything. The issue will still be there.

Ive been on the phone for the last hour. Getting passed person to person. They have no idea what is going on. Complete waste of my time. I keep telling the person i get on the phone that the issue is bigger than just me.

I too am experiencing the same issue under Big Sur. Just confirmed with Apple's technical support that this is currently under investigation by their engineers, and they are working as fast as possible to get to the bottom of this.

Same for me too using Big Sur. Just started an Apple Music trial a few days ago. Works great so far on the iPad as well as my iPhone. Partially works on my MacBook, but I can’t access any item from my library nor can I add anything new to it.

Already tried Re-Authorisation, signing out devices from iCloud, rebooting. But nothing seems to help. Can only assume this is an issue at Apple’s end. Needless to say keeping a trial doesn’t make much sense if it can’t even be used on a device. Didn’t have a problem with Spotify before. Perhaps I should change back? Would solve my problem just fine.

Working again BUT Music (formerly iTunes - I don't use Apple Music but I do use iTunes Match) is showing a bunch of duplicates as well as dupes that aren't flagged as dupes (they show the dotted cloud and they're right next to the original version). The randomness of what got duplicated and what didn't is bothersome because while my brain can handle that this entire ordeal was an Apple issue, I'd love to know why the dupes appeared and why those track in particular. Is there something about them that made duplication happen?

Alright, let's add to the problems. Outside of random dupes of songs Music decided to make random dupes of playlists. Not all playlist, just some. Some of them were renamed. I have one single playlist that is listed 27 times and yet the songs in them all belong to other playlists. I'm not happy with all the extra work I have ahead of me now.

I see many songs that are duplicated where one has a local copy and the other is not downloaded. But the not-downloaded file is more often in the "correct" (non duplicated) playlist. But not always... it's quite haphazard.

Here is my current plan to fix the mess. Note that my laptop has my entire library downloaded and I have some ALAC versions locally. So I always want to keep my local files and remove any duplicates created by this cloud merge mess.

1. For any replicated playlist, make a NEW playlist with a similar name. Example: if I have "Rock" and "Rock1" playlists, I make a new one called "Rock merged".
2. Copy all of the replicated lists into the new "merged" list. Example: Copy all the songs from "Rock" into "Rock merged". Then copy all the songs from "Rock1" into "Rock merged". If you get a message about Cloud playlists only containing cloud songs, choose "Remove from Cloud" (you will add it back after pruning). Then when you get a message about duplicates being added to the playlist, choose "Skip"—even if you "Skip" it will show duplicated songs where you have a local version and a (bad) cloud version.
3. DO THIS FOR ALL REPLICATED PLAYLISTS FIRST BEFORE GOING ON. If you start pruning before creating all the merged lists, you will miss cases where a song is in multiple playlists.
4. In each new merged list ("Rock merged"), view by Song (cmd-J to choose) and then make sure to also show (in the cmd-J dialog for view options) the columns: Song name, length, artist, album, Cloud Download and Cloud Status.
5. Sort the merged playlist by Artist. Scan through the playlist for icons in the Cloud Download—this will identify weirdness when you have a local (good) version plus a cloud (bad) copy. In my case I always want to resolve the errors by removing the cloud version. (If you don't have local copies of everything you would need to look for duplicates by reading the song name column). Make sure that the local copy is correct and/or choose which one you want by looking at the metadata.
6. Once you've gone through all the playlists like this, it should be safe to remove the duplicated ones and keep the "merged" ones. You can also convert them back into Cloud playlists. I'm not positive but if you are sync'ing playlists to your phone, you may want to first sync the merged playlist and then delete the old playlists. If you remove a playlist that you're sync'ing it's possible your phone will decide to clean up its storage and be required to re-download the merged list even though the songs are already on your phone.
7. Now you've cleaned up the playlists. You would have to do something similar by looking through all of your songs

Hm does that make sense?

Finally everything looks fine, though it has been tough to get it fixed. I am not sure if it is me or the apple side that get it fixed, but this is what I did:

1. I do remember I have output my library and one playlist that disappeared on my other devices but is still on my mac to file. But perhaps we can find a library file before I did this. I did this when the apple music is syncing forever with error messages for tons of songs, but at this moment the output files are complete.
2. I find it is the step "" that hangs forever, and this is what I find https://discussions.apple.com/thread/3534198?answerId=16908298022#16908298022 (see tmksnyder's answer, sorry I do not know how to properly cite this). The apple music is using extremely high CPU, but I am still not sure which file is wrong.
3. Sign out, quit music, sign in again. Now the cloud library is not syncing at all and the error code is 9039
4. Finally, I tried this https://developer.apple.com/forums/thread/15533 (Max's answer). And I choose create a new library, and import the files (library and the disappeared playlist) I mentioned in the first step. And now everything looks good and I can also upload my own music to the cloud right now. The disappeared playlist also shows up on my other devices. Then it looks that the original problem was caused by something crashed in the original library.

Opening iTunes while you hold the option key (shift key for Windows) if it works, this will create a new library and you can copy/move your music etc. over by using the "Add to Library" option under the file menu.

The same issue here on Macbook Pro 2015 & my other macs.

My network connection is running without interruption.

After I turned on synch music with icloud the error pops up after about ½ hour: error: 'Genius results can’t be updated right now. The network connection was lost.

Aside of the following I also made reset of my iCloud music library & tried logging out/in to Apple Music, Reauthorizing my Mac with Apple Music, restarting...nothing worked.

My Macs are running Big Sur 11.0.1

I can't access my music from iCloud using other devices running apple music like smartphone or other macs.

I have noticed something else since Big Sur upgrade...

When I run Apple Music I have no more homepage but blank page.. No redirection to "Listen" or "Explore".

Is there a relation between all these issues lately ?

MacOs 11.0.1

France

Is it uploading a bunch of music while you sync? It’s possible that it is not recognizing your library and uploading duplicates and/or re-processing your entire library.

What do you see in the activity window cmd-opt-L if I recall.

All OK here as of about Nov. 25.

But before that, I was on the phone for an hour with an Apple Support rep. As a last resort (after I troubleshot my wifi network with several reboots/resets), she had me uninstall/reinstall iTunes on my PC. She was very courteous and patient, I'll give her that. She had no idea at the time that it was a system-wide issue.

The only downside on my end is that a LOT of album artwork is now gone...maybe 25 per cent.

Not sure if anyone else has noticed this but I upgraded to Big Sur 11.1 today and it has change my Music app in ways I didn't expect nor ones that I want...and I can't seem to get them to go away.

In Smart Playlists using Songs View I now have a giant image at the top of the screen of four random cover images (exactly like what you see on an iPhone Playlist)(the randomness doesn't make sense either as it doesn't seem to be based on newest song added, oldest song, etc. It's just random) and this take up a good third of the top of the screen...and it doesn't move if you scroll down like it does on iPhone. Song View is my preferred view and this really messes with things. As if the debacle that happened last month wasn't bad enough now there are more changes for changes' sake?!?

Also, if in the Library sidebar you happen to have Recently Added as an option, you can no longer view the songs in anything other than full album and there are now zero view options to choose from to combat this. It isn't a huge deal because the Smart Playlist for Recently Added isn't affected by this change but again, change for what reason?

Has anyone else seen any of these? Do any of you have a work around for the first issue I raised?

Same here! I tried logging in/out and downloaded supplemental Catalina update and nothing. Deauthorized and authorized.

Still nothing. Obviously an Apple issue hopefully be resolved soon.
