Does anyone know if it's possible to downgrade iOS on mobile devices using JSS or how one might be able to do so on a Managed device? the new Apple update 12.2 is causing some issues with our native software and I am hoping to revert back up of our updated devices until our team is able to create a fix

Not possible trough jamf (or any other MDM Service for that matter).

Bummer, okay, any insight on how this might be done manually or are we just totally in the weeds once an upgrade occurs? I was able to prevent the auto update for the time being but apparently Apple will only let you defer and update for 90 days max

@maida.soehl Not any longer, there's a short period of time following every iOS release where Apple continues to sign and authenticate the previous version (and that ended 4 days ago). You would need the device to be plugged into iTunes and restored using the ipsw file associated with that particulate iOS device (there's a different build for each iOS device type).
