When I attempt to disable lost mode, the status is stuck on pending, and the device itself is still in lost mode. In order to troubleshoot this, I've connected the device to LTE via an activated SIM, which did not resolve the issue. I'm able to restore the devices, but I'd like to back up the data before I wipe them. I have a number of devices, iPhones and iPads, that I'm working on. Any ideas as to next steps?
