Home → Admin → System → Building Management
Choose visibility of buildings. If your district has buildings where devices are not being managed with O2O Device Manager, you can hide them from the system by turning off their visibility.
Click the box to the left of the school name
Push Turn off Visibility at the top of the page
If the visibility is off, the eye icon will have a slash through it.
You can also sync with SIS and see if an owner is attached to a particular building before making changes.
