I have a user who is an Interactor on the Site, and Interactor on the Project, and an Interactor on the Workbook but who can't click the View Underlying Data button -- the one in the attached picture. What permission am I missing?
Attached are the permissions that this user has -- for the workbook. In other words, I go to the workbook and click Permissions -- this is what I see. It seems to me that he has the permission that you've mentioned. Is something blocking this access at a different level or something?
