 But, sometimes app doesn't make it to step 3, and user loose the product with successful payment.
 Non-consumable products can be restored via getPurchaseHistory function, but consumable products can be lost.

+const purchase = await RNIap.buyProductWithoutFinishTransaction(productId);

+However, sometimes apple internally causes problem itself before `finishTransaction` which queues are not resolved which may result in failure in next purchase ([related issue #256](https://github.com/dooboolab/react-native-iap/issues/257)). Therefore, we've made another method that may resolve this kind of issue in after purchase which is to finish up the queues at the start of each purchase. To resolve this, try code like below.
+```javascript
+await RNIap.clearTransaction(); // add this method at the start of purchase.
+const purchase = await RNIap.buyProductWithoutFinishTransaction(productId);
+// to something in your server
+const { transactionReceipt, purchaseToken } = purchase;
+sendToServer(transactionReceipt, {
+  onSuccess: () => {
+    RNIap.finishTransaction();
+  },
+});
+```
+We've like to update this solution as version changes in `react-native-iap`.
