I can see my email ID not in Admin role but just as member in people tab. So the one in agent role resent me invitation with Admin role. Even though I accepted that, I did not see my role changed from member to Admin. So I followed a suggestion on a forum, suggested to change role in iTunesConnect. So the agent added my role in iTunes connect with admin role and resent invitation. Now I can see my role in iTunes connect as 'admin' role. But in people tab in apple developer account my role is still in member. Can you please suggest me how to change my role here to admin?
Sending a new invitation is not the right approach.
Someone with admin or team agent role needs to edit your existing user to "Change to Admin".
