Issue Description
A QuickAdd package download from the enrollment URL (https://Your.Jamf.Pro.Here/enroll) instead of the MDM profile.
The most common reason for this would be an expired Apple Push Notification Service (APNS) certificate in Jamf Pro. When this expires, it disables the MDM first enrollment processes.
Troubleshooting Steps
Renew the APNS certificate following the information in Renew MDM Push Notification Certificate.
Reattempt enrollment using the User Initiated Enrollment URL.
