To troubleshoot OneDrive not showing recent changes to a file, try the following:

1. Check the Activity view in the OneDrive folder, to make sure that the changes have been uploaded to the cloud.
2. If they have been uploaded, they should show in the Activity view.
3. Check the Share setting of the file for possible incorrect settings.
4. If the setting is incorrect, make sure to synchronize the updated Share settings.
5. If the setting is correct, delete the old version of the file and the backup that OneDrive creates.
6. After deleting the old version and backup, resave the file in OneDrive.
7. Finally, check to make sure that the file has been updated and the changes are now displaying.
