How do I renew my Push Certificate in SimpleMDM?

To renew your Apple Push Certificate in SimpleMDM, navigate to Settings > Push Certificate, click 'Renew', and then follow the instructions that appear on the screen.

When renewing your Push Certificate, be sure that you are renewing the existing certificate (using the same Apple ID that was used to set it up initially) and not uploading a new one. Uploading a different certificate will cause any devices already enrolled to stop functioning with MDM until they are re-enrolled.
