Hi Ramon,If I am in A, and I can add "All" as well as A in an audience. This means that when I am creating a delivery, I can send email or SMS delivery to profiles which are outside of A as well ("All").This is confusing because while creating a delivery , I can only create it if the campaign on which it is created belongs to the same org unit A. But, for audience I am able to send it to org unit "All" as well.
