In all of our years of using JAMF School with shared iPads, we have had to manually reset a large number of iPads with each update. Even with the last update! This took us three days of work with two people. What's wrong with you that after years you still can't figure out that the JAMF School update function doesn't work with shared iPads? We're going crazy with iPads here!
And yes, we know about logging out users and clearing the cache before updating!
