The method to access attached Command Centers has been enhanced in this 3.3 release. Also, users who log in with read-only access can choose to open to either the home page or a zone map. See Portal-to-CC Login for Portal 3.2.7 Users for the Lumeta Portal 3.2.6 and 3.2.7 login options. 

Controls for superusers
Only a superuser can add a Command Center to the Portal, or delete one. Only a superuser can manage users. Accordingly, the Settings menu and the Edit button only display on the Portal landing page for superusers.
