Apple MDM: The token was not updated after the user installed the description file(.mobileconfig)

Our MDM customers often claim MDM push is not delivered to device and cannot manage devices via MDM.

The user first uninstalled the old description file and then installed the new one, but after the new description file was installed, our mdm server did not receive any notification from Apple about updating the token, only received an Authenticate message

We tried to restore network settings but it did not work. We hope to get your help to solve this problem. Currently, we can't figure out where the problem is.
