I just added a couple of friends as "testers" for my app. I can assign administrators, developers, testers and analyticers and according to
https://developers.facebook.com/docs/apps/security
only admins and developers must have a developer account (at least facebook mentions this requirement only for these two roles).
So, all my friends have a "pending" next to them in my roles-overview and they say that do get a notification saying I invited them, but cannot accept without becoming a developer.
Did I make a mistake, or did facebook just forget to list this requirement on their roles-page?
Would appreciate any clarification. Thanks :)
