I created a mobileconfig file on our self-developed MDM server and used Apple Configurator with a USB cable to prepare the device.
However, the profile installation failed and show the mdm payload is invalid must to be removed.
I suspect that the issue might be related to the CA (Certificate Authority) in the configuration, even though I have provided the ROOT SSL CA and the .p12 file.
What CA file should I include in the mobileconfig to resolve this issue?
using Apple Configurator to edit the mobileconfig file, but the MDM service is no longer displayed. How should I handle this
