User Profile

This looks like a really fun & powerful feature! Is it possible to use the new Nearby Interaction between devices owned by the same user? If so, is it possible for the user to grant permanent permission for us to do this instead of repeatedly at the beginning of every session?

I'm currently testing introductory pricing for one of our apps. I've configured the introductory price in iTunesConnect, and the introductoryPrice `SKProductDiscount` is present in the `SKProduct` that I receive from my `SKProductsRequest`, so I can show the details of the deal to the user.When actually purchasing the product (an auto-renewable subscription) in sandbox mode, the price that appears in the confirmation pop-up is the full-price. It doesn't mention anything about the introductory price or period.1. Is this just a(nother) limitation of the sandbox for testing IAPs, or is there something else that I should do to explicitly put the introductory price through the queue instead of the full price?2. If there's nothing I need to do to explicitly use the introductory price instead of the full-price. Is there another way that I can choose to only provide the introductory pricing to certain users?
