Use the business picker when your account belongs to more than one business. The navigation, Billing, Staff users, and available locations update to the selected business.
Within a business, use the location selector in the sidebar to choose the venue you want to operate or configure. The Location overview, under the location in the sidebar, contains its lists, Check-in actions for Public check-in and kiosk mode, its TV display, occupancy, and floor plans.
Before changing a list or adding a walk-in, check both the business and location name. This prevents entries and configuration from being added to a similarly named venue.
If a business or location is missing, ask an administrator to review your invitation, role, and location assignments.
