We have a ticket opened with JAMF support and they told me the same
thing about the Wallpapers and Automated management in the smartgroup.
We use this for all of our devices and are running into the same issues
with SCEP errors during provisioning.
I came here for the same questions. We have iPads that have an in-house
app that is using a SDK build; iPad OS 16 is asking for the iPads to
have this enabled. Trying not to touch each device (about 100) if
needed.
