buySubscription on iOS failing multiple times for users

Platforms you faced the error (IOS or Android or both?)

Expected behavior

Error message should distinguish between user cancelling purchase and user experiencing an error.

Actual behavior

I'm noticing that a large number of my users are getting an error when attempting to purchase a subscription. In my error logs, I'm seeing the CANCELLED error message when they try to buy. Of course, many of these users could actually be cancelling their transaction. However, I'm curious to dig into this further because there are many users that attempt to make the purchase multiple times. For example, some users will press purchase 4 times in a row and are not able to complete the transaction--they all show the CANCELLED error message. I can't figure out if they are just confused and cancelling the purchase or if it's breaking due to an unknown error.

Attached is roughly the code I'm using.

Real Device

Steps to reproduce the behavior

I can't reproduce it myself. I'm only seeing the activity through logging.

Actually, this PR was updated in #291. Apple doesn't seem to provide the correct error message natively (if I am correct). But then if we revert the PR it will provide only Enligsh error message. @mars-lan Hope you can look at this if you are available.

Thanks @hyochan

Is there anything I’m doing obviously wrong in the attached code?

I saw someone commented that it may be caused by an Invalid Product ID. Are there any gotchas that I may be missing regarding Product ID?

It’s strange to me because it works fine for me in the US but breaks for users in Vietnam, Cambodia and other countries.

@noahhayes I've briefly saw your code and seems to look ok. I'd suggest you to use componentDidMount instead componentWillMount tough.

I hope you to check some tax agreement for Vietnam, Cambodia or other countries if you are facing issue in ios.

I believe the original question has nothing to do with the localized description, but the actual error code (SKErrorPaymentCancelled that got mapped to the standardized "E_USER_CANCELLED" here). #291 didn't touch that part of the code so reverting it won't address the issue.

@mars-lan Thanks for confirming. I did not had time to look through that. I'll come back when I am available.

@noahhayes What happens when you change the code like the below?

  onPressPurchase() {
    this.setState({ purchaseLoading: true }, () => {
      RNIap.buySubscription(PRODUCT_SKU)
        .then(() => {
          this.setState({ purchaseLoading: false });
        })
        .catch((err) => {
          this.setState({ purchaseLoading: false });
        });
    });
  }

I have something similar where they go through the flow, have to change payment method (for example) and then the component doesn't return anything after the transaction is completed.

In this case, we make them restore the purchases and everything is fine.

@edo1493 Could you provide some codes? Do you mean you've just called getAvailablePurchases to solve this issue?
