We have about 200 iPads with IOS 6.1.3, and we try to enroll them by the url. The two profiles CA Certificate Payload & MDM Profile both download and install successful. It also says enrollment complete. But Self-Service do not appear on the iPad home screen and the iPads' info do not upload to casper. The inventory only show the device model & location info, and the rest are all blank. Does any body know what the problem is? Thanks.
