I can see/send invites to non-app user friends on canvas app but not on android/ios

I am using the facebook sdk for unity and testing out app requests using the following call:

 FB.AppRequest(
             FriendSelectorMessage,
             null,
             FriendSelectorFiltersArr,
             excludeIds,
             maxRecipients,
             FriendSelectorData,
             FriendSelectorTitle,
             Callback
             );

The above call returns a list of all my friends when testing in the canvas version of the app, however when I compile for android/Ios, I only get a list of friends who have played the app??

Is there anyway I can see all friends on ios/android as well?
