When I try to access iAd workbench it just returns me to the login screen with no error messages. I dont have any other users/roles on my developer account and therefore assume that by setting myself as default for all the roles(including marketing" in "agreements, tax & banking" that would be sufficient.
However, when I check in users and roles my only roles are "admin and legal". I try to add the marketing role but it is greyed out. Do I really have to create another user to access iAds?
