As I understand we got bitten by the PreStage Enrollment Issue of 10.11 because we have a PreStage Enrollment using "Automatically assign new devices" to this PreStage. (Doing more or less the same as saving before the scope updated.)
Now our workflow is broken until I get this PreStage erased.
Since it is broken I cannot delete this PreStage via GUI. I see no API option.
I would appreciate it if you could give me a hint how to delete the broken PreStage Enrollments correctly.
