We noticed that your app uses Facebook login for authentication purposes but does not include account-based features offered by that site, which does not comply with the App Store Review Guidelines.
In order to use Facebook for authentication, your app must include significant account-specific functionality from Facebook. For example, your app should include sufficient account-based features from Facebook other than pulling profile information or sharing on the user’s page.
Next Steps
Please revise your app to implement your own authentication mechanism, or incorporate significant account-specific functionality from Facebook.
If your app does include additional account-specific features from Facebook, please provide us with details on where we can locate these features in your app.
