freely access to app's feature that are not account based impossible but...

Hi,

My application requires users to register and enter a postal address to operate. From this postal address, registered users can see the ads around them within a 30km radius, and only these ads.

I've had the same app validated 12 times with the same functionality on the AppStore, but today I'm asked to open the app to allow free access to the app's non-account based features.

This is simply impossible since it is a proximity social network. It was never intended to open the application without registering first. How to solve this? Thanks

Regards
