I have un managed one ipad. How can I re manage it?
Need an answer to that too.
You need to reenrol it into Jamf Pro.
Go to Safari and type the URL of your Jamf Server and type /enroll at the end and follow the steps for User Initiated Enrollment (UIE).
This should solve your issue.
Just want to check, will there be a device license cost be charged to Unmanaged iPad's? if I wanted to keep it there for inventory purposes?
