Why does the location not appear within the Visit configuration?

If a location is added in the Visitor configuration, it must also be enabled within the location settings.
To do this, navigate to Settings > General > Locations and check the box labeled ‘Visitor kiosk enabled’ for the desired location.
Enabling this option designates the location as active and available for use within GoBright Visit.
