Facebook API "This app is in development mode"
FacebookFacebook Graph-ApiFacebook Problem Overview
What does "development mode" mean for a facebook app? I find no exact explanation of what I can and can't do while in development mode and what's the relation with the "Not available to all users because your app is not live".
Some people also refer to it as "Sandbox mode" so I have a lot of confusion between "development mode", "sandbox mode", "live vs not available to general public"

I had also faced the same issue in which my FB app was automatically stopped and users were not able to login and were getting the message "app is in development mode.....".
Reason why FB automatically stopped my app was that I had not provided a valid PRIVACY policy & terms URL. So, make sure you enter these URLs on your app basic settings page and then make your app PUBLIC from app review page as described in above posts.

I have the same problem while integrating the Facebook SDK for login.
I'm suggesting below approach for development mode > you can test all things if you are login with same account, which is used for 'developers.facebook.com' and if you want to use another accounts then you need to add Roles for that particular app, for that you can add developer or testers by using fid or facebook username.
Eg: - Select the particular app > Roles and then add developer or testers.
