I'm New to IOS management. We don't have any licenses for them yet but we were told we could go ahead and enroll a couple devices to see if it was something we wanted to get in to. I'm trying User Initiated enrollment through the enrollment URL but when installing the MDM profile it fails. When I click Install for the profile on the device it returns with "Profile installation Failed. The Server certificate for myjss.com:8443//enroll/ profile is invalid." I'm using the JSS built-in certificate but that installs onto the iPad before installing the MDM profile. Under the signings certificates section of the profile, two certificates are there. One until 2022 and one until 2027.
