You cannot make a map and then share it to a user group, I've tried different ways in doing so and it just will not save it onto the map. I can assign it to a specific user, but I really need it to be assigned to a host group in my environment. I did post this on reddit to have others on 6.0.2 attempt it and same result so I know it wasn't just me.{}

Steps to reproduce:

1. Monitoring > Maps -> Properties of a map i created -> Sharing tab -> selecting a user share and then it shows up, i select read only, and click update. Go back in and I can see it did not add the group.

Result:

No shared  user group was added to the map.

Expected:

A shared user group should have been added to the map.
