Intune pushes the IOS DDM policy (to push version 18.7.8 to devices using 17.X, with a set deadline) to iOS devices using cellular networks. However, the update fails to succeed. A pop-up window appears indicating "Download and Install", and clicking on "Download and Install" shows no progress bar. But if the device enables Wi-Fi, a progress bar will appear for the download and installation process. I would like to confirm whether there are any restrictions on DDM pushing system upgrades to devices currently using cellular networks.
