Is it possible for a contact to have multiple vids? When I point to a specific contact at the CRM UI in the browser, I am taken to the contact page but the vid at the browser changes. It is like the contact has multiple vids. In fact, I can use any of those vids at the API and I get the info for the same contact. How is that possible? I thought that the vids were unique. Does this mean that vid is not the primary key for the contacts?
