Make sure you complete these final steps to run app ads. Then you or anyone listed under an ad account linked to this app in the app dashboard can run ads.
Resubmit App - After you add a Facebook SDK and App Events to your app, you should resubmit your app to the app stores where it's available for download. You need to do this because you changed the source code.
Create and Run App Ads - You or a non-developer can now create and run app ads. Learn more about creating ad campaigns for your apps at Advertiser Help Center, Create a mobile app ad campaign, which tells how to create app ad campaigns with Ads Manager or working with your Facebook Marketing Partner. You can also create and run ads with the Marketing API; see Marketing API, Ads Management.
