Is it possible to listen on all interfaces on iOS, in a way equivalent to listening on 0.0.0.0 for ipv4 on linux/windows/mac? I tried both 0.0.0.0 and the ipv6 equivalent and they do not seem to work on iOS.

We're testing in-app purchases in our iOS app, and Product.products(..) returns an empty vector in the sandbox environment, both when building & running in xcode and on testflight. We've eliminated all the obvious reasons: Paid App Agreement is done InAppPurchase Products are in Ready to Submit The ProductId's are matching Sandbox tester account is set up and logged in on testing device Currently we're out of ideas for why the IAP purchase products are not showing up - would appreciate any help!
