c# - In App Purchase issue after purchase -

I got a strange behavior with the IP OS on IP, when the purchase is done from the IAP work, the request does not run at all, It's somehow to leave it, I've caught a try, but there are no exceptions at all. If you put a glance at it, then I appreciate that I know that you need more information.

  Waiting for private async zero Button_Click_1 (Object Sender, RoutedEventArgs E) {var list2 = CurrentApp.LoadListingInformationAsync (); Var noads = listing2.ProductListings.FirstOrDefault (p = & gt; P. Value.ProductId == "RemoveAds" & amp; P. Value.ProductType == ProductType.Durable); Try {Waiting for CurrentApp.RequestProductPurchaseAsync (noads.Value.ProductId, False); // There is nothing here MessageBox.Show ("Done"); } Hold (Exception pre) {Message Box. Show (ex.InnerException.Message); }}
