Facebook App Details rejected for not appearing to integrate Facebook Login

view story

http://stackoverflow.com – I keep having my app details page rejected with this message: Your Android app does not appear to have Facebook Login integration. Please either implement Facebook Login or remove this integration as a listed platform in the developer app. See more details here I do use Facebook Login in my app. Who can I contact to resolve this issue? What really does not make sense is the free version of my app was approved, but the paid version keeps getting rejected, when they integrate Facebook Login the exact same way! Thanks, Ben (HowTos)
