Do I need to have seperate Facebook App ID for my same app in Android and iOS?

Question

For Facebook rejection detail Image refer this link
My facebook app review got rejected recently for some reasons not related to this question. But in the reasons provided by review team there is this line

If any of your platforms, (iOS, Android, other) don't use Facebook Login, please remove that platform from Settings. Please also ensure that you have a different App ID for the second platform.

So Do i need separate Apps in facebook developer console for my same app in two different platforms?

Answer 1

No, You don't need a different app, one app can be used by multiple platforms (Web, iOS, Android). Make sure you have removed the extra platform check the screenshot. Following are the steps to remove the extra platform.

Click MyApp -> Settings -> Basic -> Scroll Down

You will see similar to the attached screenshot. Click on the cross for the platform you are not using and save. Try submitting the app again.
