I have a user that receives a window noting:
Unmapped Global Collections Found
This is when adding Global Collections and Device Families in bulk to new NCM policies.
Release : 20.2
Component : Spectrum Core / SpectroSERVER
The device family needs to be added to each Global Collection. You cannot apply it to just one of the GC. It needs to be applied to all GC.
You have to manually add the device family to each GC in the policy application window. The error came from only applying the device family to 1 GC.
