I'm developing an iOS/Android app with Facebook sign in. The app sign in correctly asks for basic and extended permissions (email, post on behalf). However, while trying to authorize the app via browser on PC (safari or Chrome) Facebook only asks for basic user info permissions.
I'm following this tutorial https://developers.facebook.com/docs/howtos/login/server-side-login/ and everything works except for this difference in what permissions Facebook asks for.
Any suggestion on how to make it work correctly on browser too?
