Primary Contacts can only be assigned by Admins. They are assigned when a Location is created.
If you are an Admin and need to change the Primary Contact for a location, you can do so on that Location’s page.
Go to the Locations Tab
Select a Location
Scroll down to Team Member
Scroll to the user and Select ‘Assign as Primary Contact.’
The Primary Contact will receive an email confirming their status and responsibilities for the location.
