To fix OneNote sync issues, you can try the following steps:

1. Check Sync Status: Right-click the notebook in OneNote and select "View Notebook Sync Status" to check for any error messages.
2. Force Sync: If there are unsynchronized pages, click on the page to give it focus and force a sync.
3. Check File Size: Ensure that no notebook section exceeds 50 MB, as larger sections may cause sync issues. If any section is too large, consider splitting it into smaller sections.
4. Internet Connection: Make sure you are connected to the internet and that your account is authenticated (signed in).
5. Restart OneNote: Sometimes, simply restarting the OneNote application can resolve sync issues.
6. Check for Updates: Ensure that your OneNote application is up to date, as updates often include bug fixes and improvements.
7. Backup and Restore: If sync issues persist, you can check for backups and restore from them if necessary. Navigate to File -> Open Backups to find your backup files.

If these steps do not resolve the issue, you may need to consult Microsoft Support for further assistance.
