Topic ID does not match the existing certificate in INTUNE
Received the following error while updating the expired Apple MDM Push Certificate. Topic ID does not match the existing certificate in INTUNE.

The error is quite common in INTUNE when users are trying to date a certificate which is going to be expired or is already expired.
It occurs if there is a mismatch between the enrollment token in tune and Apple Business Manager. Or the account used to generate the Push certificate is not matching the earlier or expired push certificate.
If you come across this issue, make sure you are using the valid account to generate the push certificate on Apple Identity store.
