The tune-sync apps use existing cloud drive providers like iCloud and Google Drive so that your private data is not stored on our servers. For some cloud providers, the hidden files that tune-sync apps use to sync data will show up as files that you have "recently changed." We have mostly eliminated that for iCloud, but Google Drive doesn't give us a way to hide that activity. We would if we could. :-)
These cloud providers normally work great… until they don't. If things seem "stuck" — you make changes on your iPhone and they're failing to show up in your Windows app — here are some techniques that can sometimes get data flowing again, roughly in order from gentlest to most drastic.
iCloud Drive
Mac
- There's no explicit "pause" button on Mac. Open System Settings → Apple ID → iCloud → iCloud Drive, then toggle it off, wait 30 seconds, and turn it back on. This forces a fresh sync handshake.
- Toggle Wi-Fi off and back on — a common, low-risk way to reset the network path iCloud is using.
- If it's still stuck, some people force-quit the
birdprocess (Apple's iCloud sync daemon) from Activity Monitor. macOS restarts it automatically within a few seconds — safe, and doesn't touch your iCloud settings. - Sign out of iCloud and back in (System Settings → Apple ID) — last resort, as it can take a while to re-verify everything.
- Restart the Mac.
- Check your iCloud storage quota (System Settings → Apple ID → iCloud) — a full account silently stops new data from syncing.
- Check Apple's System Status page for an iCloud Drive outage.
Windows
- Open the iCloud app, uncheck iCloud Drive, wait 30 seconds, then re-check it.
- Quit the iCloud app from the system tray and relaunch it.
- Sign out of the iCloud app and sign back in.
- Restart the PC.
- Check your iCloud storage quota at icloud.com/settings.
- Check Apple's System Status page.
iOS
- Toggle Airplane Mode on, wait 30 seconds, then off — a quick way to force a fresh connection.
- Go to Settings → [your name] → iCloud → iCloud Drive, turn it off, wait 30 seconds, and turn it back on.
- Force-quit the tune-sync app (swipe it away in the app switcher) and reopen it.
- Restart the iPhone or iPad.
- Check Settings → [your name] → iCloud for your storage quota.
- Check Apple's System Status page.
Google Drive
Desktop app
- Click the Google Drive icon in the menu bar (Mac) or system tray (Windows) → Pause syncing. Wait 30 seconds, then Resume syncing.
- Quit Google Drive entirely and relaunch it from your Applications folder or Start menu.
- Sign out of the desktop app (Settings → Disconnect account) and sign back in.
- Restart your computer.
- Check your storage quota at drive.google.com/settings — a full Google account stops new files from syncing.
- Check the Google Workspace Status Dashboard for a Drive outage.
Android
- Open the Drive app and pull down to refresh.
- In Android Settings → Apps → Google Drive → Force stop, then reopen the app.
- In the same Settings screen, clear the app's cache (not "clear data" — that signs you out).
- Check Settings → Apps → Google Drive → Mobile data & Wi-Fi for background-data restrictions.
- Check your storage quota at drive.google.com/settings.
- Check the Google Workspace Status Dashboard.
OneDrive
- Click the OneDrive cloud icon in the system tray (Windows) or menu bar (Mac) → Help & Settings → Pause syncing → pick 2, 8, or 24 hours. Then reopen the menu and choose Resume syncing (or just wait it out).
- Close OneDrive from the tray/menu bar icon, then relaunch it from the Start menu or Applications folder.
- Sign out (Help & Settings → Account → Unlink this PC) and sign back in.
- Restart your computer.
- Check your storage quota at onedrive.live.com.
- Check the Microsoft 365 Service Status page for a OneDrive outage.
Still stuck?
