Additionally, we noticed that your app appears to be a pre-release, test, or trial version with a very limited feature set. Apps that are in beta form, or that are for demonstration or trial purposes only, are not appropriate for the App Store and are not in compliance with the App Store Review Guidelines.
Specifically, the app features an area for banners but there are not banners present.
Please refer to the attached screenshot/s for more information.
It would be appropriate to complete, remove, or fully configure any partially implemented features and/or to remove any references to "demo", "trial", "beta", or "test" in your application description and release notes, and from within the app.
If you are interested in conducting a beta trial for your app, Ad Hoc distribution is available to broaden your test user base. Information on Ad Hoc distribution is available in the iOS Developer Program User Guide.
