same issue with me from yesterday.Did you find solution?
From my understanding, your application does not have enough functions to be able to publish at App Store. If you look closer to the reply you received:
"We encourage you to review your app concept and work towards creating an app that offers customers an engaging and lasting experience that also meets the App Store’s high expectations for quality and functionality. For example, an app for a restaurant should offer more functionality beyond a standard mobile website that includes its phone number, address, and hours. You should instead include functionality like table reservations, mobile ordering, etc. that do not currently exist on the mobile website."
I think you need to follow what they are telling you and change/add these needed functions to your application so you can be able to publish at App Store.
me too. Although a similar review of the App Store is possible, the Apple review team will not explain any other applications and reasons to you during the communication, so it needs attention. But from the minimum characteristics of 4.2, the definition is very vague, and the problem lies here.
