I had a botched upgrade to 10.2.0 Monday and was less than amused by their decision to be closed w/o any notification (other than when you're stuck and calling the support line/opening a ticket online). Not even an on-call support person. very unacceptable. I was grateful for the slack community on #jamfnation that was able to resolve the issue, but jamf relying on the community to handle support is not a good business practice.
We've been with jamf for a LONG time and will chalk this up to a brain fart on behalf of their management.
