What is the maximum number of users that can be added to my operation in Granular Insights, and what will they see when I invite them?

You can add an unlimited number of people to your operation and control their level of access by specifying a role for each individual: 

• Viewers: can view fields only
• Editors: can view, edit and add fields
• Admins: can view, edit and add fields, as well as manage operation settings
