Why isn't sync working on Apple Music?

When you encounter a "This song is not synced on your device" message on platforms such as Apple Music, Spotify, or YouTube Music, it usually means that you may not be able to sync your music across devices due to the following reasons:

🔁Sync is interrupted - Songs are not fully uploaded/downloaded to all devices' cloud libraries.

🧩Version differences - Audio tracks may be local files, special versions, or not available in all device service catalogs.

🌐Region restrictions - Songs may be region-locked, or some devices may be deactivated.

👨🏻Account anomaly - Different devices may be logged in to different platform accounts.

8 Fixes on Apple Music Library Not Syncing

If the sync fails, you can try the following solutions step by step; if you need to quickly transfer music, you can also go directly to the next section to get a simple and professional iTunes replacement to easily transfer your purchased and unpurchased music across devices.

Fix 1. Check your internet connection

Sync requires a stable network. Weak signals can cause failures or delays, and we generally recommend that you prioritize trying to switch Wi-Fi/mobile data, restart your router, or refresh your network connection (i.e., turn off/back on airplane mode).

If the Apple Music “This song is not synced across your devices” message persists, you can reset your iPhone network settings to fix it:

Go to Settings > General > Reset > Reset network settings.

Fix 2. Check Apple system status

You'll also need to check that Sync Library (also known as iCloud Music Library) is enabled on all of your devices by going to Apple's official system status page to keep your music collection consistent across all your devices.

If you see a yellow badge on your server, it's under temporary maintenance, and you can wait a while or contact Apple Support for help. If all servers are green, we recommend that you go ahead and try other workarounds.

Fix 3. Re-add the song to your library/playlist

Some users have reported that deleting and re-adding songs resolves the Apple Music not syncing between devices issue. When you re-add a song on Apple Music, the song is re-downloaded from the server to your iPhone.

Step 1. Open Apple Music on your iPhone and search for the problematic song/album.

Step 2. Click the ... icon and select Delete.

Step 3. Search for the song again and click +Add to the library, then play it again to test whether the problem is solved.

Fix 4. Update Music app/iTunes/iOS system

Apple always recommends updating iOS and iTunes to the latest version to avoid various compatibility issues. Follow these steps to update:

• Apple Music: Go to the App Store to get the latest version

• iTunes: Click on the menu bar Help > Check for Updates

• iOS: Go to Settings > General > Software Update, download and install available updates

Fix 5. Enable Sync Library in settings

If you disable the sync library setting on your iPhone, then the Apple Music Library not syncing across devices issue will also occur. You can follow the steps to try to enable the feature.
