iOS User Enrollment isn't fully working


we're experiencing some strange issues with the iOS User Enrollment for user owned devices (BYOD).

The devices are marked as not compliant with the message "No screen lock set", even there is definitely a screen lock set. Afterwards rolling out a user policy for adding the corporate M365 account fails as well. Installing apps on the other hand works fine.

When we enroll the same devices with device enrollment, everything works as expected even if we say the device is owned by a user.

Any idea, why this happens?

Thanks and regards,
