Unity IAP: product.hasReceipt alway return false with non-consumable product after restarting app on iOS

Question

Hi guys. I'm working with Unity IAP plugin. When app starting, i want to check a non-consumable product was bought or not. This is the code i used:

 public bool IsPurchased (string productID)
     {
         Product product = m_StoreController.products.WithID (productID);
         if (product != null && product.hasReceipt) {
             return true;
         }
         return false;
     }

Even i have already bought a non-consumable one but the product.hasReceipt alway return false on iOS platform (sandbox). I expected it should alway return true as i bought a non-consumable product. Somebody tell me why? Thank you in advance.

I found a solution to work around this problem by using apple receipt. This is the snip code i use. Hope it can help you guys

 var builder = ConfigurationBuilder.Instance (StandardPurchasingModule.Instance ());
 var receiptData = Convert.FromBase64String (builder.Configure<IAppleConfiguration> ().appReceipt);
 var receipt = new AppleValidator (AppleTangle.Data ()).Validate (receiptData);
 foreach (AppleInAppPurchaseReceipt productReceipt in receipt.inAppPurchaseReceipts) {
                 if (productReceipt.productID.Equals (productID)) {
                     return true;
                 }
             }
             return false;

I still don't understand why product.hasReceipt return false :(

var receiptData = Convert.FromBase64String (builder.Configure ().appReceipt); return "This is a fake receipt. When running on an apple store, a base64 encoded App Receipt would be ... " and throw FormatException. I need to test IAP before the app is on Appstore. what should I do???
