Apple Music won't sync across devices.

pang212,

Thanks for clarifying that you're deleting from the library and adding songs, and it still doesn't update across your devices. You mentioned that you've toggled Sync Music off and back on, have you actually logged out of your Apple ID in both iTunes & App Store on iOS devices, the Music app or iTunes on any computers as well?

These could be determining factors.

If you haven't yet, try this:

1. Log out of your Apple ID in iTunes & App Store on all devices. (It will remove any content you've made available offline in Apple Music.)
2. Restart all devices.
3. Log back into one device and make sure that your Apple Music library loads.
4. Log back into all other devices.

Test to see if it syncs across devices this way. If possible, it's best to sync using Wi-Fi. If you're using more than two devices, try to determine if there is a disconnect with just one. For example, if you have an iPhone, iPad, and a Mac - does it sync from the iPhone to the iPad, but not to the Mac?

Hopefully this helps!

pang212,

Thank you for reaching out at Apple Support Communities today. If I understand correctly, your Apple Music changes aren’t syncing across all your devices, and you have to turn Sync Library off and back on to get it to sync. 

If I have this correct, I can see why you’re looking for a resolution. 

When you select “Remove” on your iOS device to delete a song, are you choosing “Remove Download” or “Delete from Library”? Removing the download will only remove it from your local device. Deleting from your library should remove it everywhere. 

Delete music, movies, and TV shows from your device - Apple Support

Cheers.
