Using Configurator 1.2.1 restoring to a backup of iOS 6.1.3 and an enrollment profile created with JSSv8.7 along with a WiFi configuration profile created in Configurator. I've gotten this to work with 103 devices, up until a few hours ago, but now when I try the enrollment profile installs but the device never really enrolls - doesn't show up in the JSS, no Self Service profile.
I've heard of this happening in the past but hadn't heard about it recently. Is there a known-good workflow for this situation?
