As an organization with an enterprise account over 30,000+ employees system admins need to have the final say if a user should be considered a paid member OR a viewer (free). I understand that we can do this review during the true up period but with that many users its a maintenance nightmare when users who are NOT a system admin get to decided if a user becomes provisioned over and over again via sharing vs a system admin locking a users account into a user type.
If I create a user as a Viewer, I do not want the user to have any ability to become a provisional user without admin intervention. They should not have the ability to create a new sheet and become a provisional user.
