Goals

I want the Facebook app to redirect back to my app after login process is initialized while logged out on the Facebook app.

Expected results

I want the Facebook app to redirect back to my app.

Actual results

Facebook app stays in place, directs me to the home page.

Steps to reproduce

-Log out of Facebook on web and the mobile app
-Log in using the Facebook Login button placed inside the app
-See that the redirect mechanism back to the main app is broken, but it works fine if the user is already logged in on the FB app
