If you're experiencing issues with QuickNote not syncing your notes across devices, follow these steps to resolve the problem:

1. Check Your Internet Connection: Ensure that all devices are connected to a stable internet connection. Syncing requires an active connection, and disruptions can cause delays or failures in synchronization.

2. Verify Account Login: Confirm that you're logged into the same QuickNote account on all devices. If you're using different accounts, your notes won't sync across them.

3. Refresh Sync Manually: Sometimes, the sync process may stall. To manually refresh, go to the settings menu in QuickNote and select the Sync Now option. This should force the app to sync your notes immediately.

4. Check App Updates: Make sure that QuickNote is updated to the latest version on all your devices. Outdated versions may have bugs that could impact syncing.

5. Reboot Your Devices: Restarting your devices can resolve many temporary issues, including syncing problems. After rebooting, open QuickNote and check if the sync issue persists.

6. Clear Cache: If syncing still doesn't work, try clearing the app's cache. This can remove any corrupted data that might be causing the problem. Be sure to back up your notes first if you haven't already.

If you've tried all the steps above and are still facing issues, consider contacting QuickNote support for further assistance.
