Why is OneDrive showing missing files or folders after a OneDrive update?

1. Check the Recycle bin of OneDrive to see if the missing files are in there.

2. Check if the device is connected to the internet, as OneDrive may not be able to access files without an internet connection.

3. If files are missing after the OneDrive update, check if older versions of the files are stored in the OneDrive History page.
