Apple Store rejects app using ground plane due to missing AR markers

Hi,

we have an app that we would like to publish on iOS, but Apple keeps rejecting it because we don't provide any AR or QR markers.

The app (developed in Unity 2018.2) uses Vuforia only for ground plane detection, so no markers are needed. Does anyone know how to get around this issue? Apple doesn't give us much information about the problem.

Thanks for your help.

P.S.:

Here's the message they provide with the rejected submission:

Guideline 4.2 - Design - Minimum Functionality

We noticed that your app includes an AR or QR scanner but does not include any additional content or functionality unless the user has access to the AR marker or QR code. While we understand that your app displays additional content when an AR marker or QR code is scanned, to users who do not have access to the AR markers or QR codes, your app only appears to display a camera view.

Next Steps

We encourage you to provide your users with additional content in your app, including directions on how to use your app and information on how to obtain any necessary AR markers or QR codes.

To ensure users have the best experience, apps should provide valuable utility or entertainment, draw people in by offering compelling capabilities or content, or enable people to do something they couldn't do before or in a way they couldn't do it before.
