So in JSS, you are able to create search groups to whatever you'd like. In that search, you can view the listed iPads that meet the fields of that search. So for instance, I have a search group saved labeled "Self Service Needed", and in the settings it selects what iPads do not have Self Service installed. I can view each single iPad that does not, and look as to why it does not.
That being said, I have made an iOS version check group so that I can see what version iOS the iPad's have to see who has updated and who has not. I can click "View" and see the versions listed by the iPads, but that's 933+ iPads to look through. Is there not an easier way I can create a search? I know with the MacBooks, you can have the policies created and actually see a pie chart of how many have done or not done said policy.
