So we are playing around with using Configurator 2 (now available in the App store) to configure some of our iPads. One quirk we ran into is the server URL you use to set up your MDM in Configurator 2. We discovered you need to use the URL:
https://jss.organization.org:8443/mdm/ServerURL
instead of
https://jss.organization.org:8443/configuratorenroll
Just FYI in case anyone else runs into this issue. So far Configurator 2 is much, much better and easier to use.
