Prerequisite: After the MDM APP issues the command, the camera on the phone is no longer visible (unusable). After upgrading to iOS 26.1, the isSourceTypeAvailable: UIImagePickerControlSourceTypeCamera method keeps returning true when the camera is unavailable. The isSourceTypeAvailable: UIImagePickerControlSourceTypeCamera method on iOS 26.0.1 is normal, returning false when the camera is unavailable and true when it is available.

Our MDM customers often claim MDM push is not delivered to device and cannot manage devices via MDM. The user first uninstalled the old description file and then installed the new one, but after the new description file was installed, our mdm server did not receive any notification from Apple about updating the token, only received an Authenticate message We tried to restore network settings but it did not work. We hope to get your help to solve this problem. Currently, we can't figure out where the problem is.
