IOS device enrollment Error

Hello,

I have an issue with the iOS User Enrollment for user owned devices, used for corporate purposes.

The devices are marked as not compliant with the message "No screen lock set", even with multiple security features in place.

When I enroll the same devices with device enrollment, everything works as expected but still indicates not fully managed.

Any idea, why this happens and any way around it?

Thanks and regards,
