How to detect subscription renewal?

Is purchaseUpdatedListener called again, when a subscription is renewed? If not, what is the best way to detect this event, when not using server notifications?

@kayamy Yes, here is the basic function:

private async checkForSubscriptionUpdates() {
    // check if user was subscribed (information is stored in redux store)
    if (!this.isUserSubscribed()) return;

    if (Platform.OS === 'ios') {
      const receipt = await IAP.getReceiptIOS();
      await this.processReceipt(receipt);
    }
    if (Platform.OS === 'android') {
      const subscriptionPurchase = await this.getMostRecentSubscriptionPurchase(); // uses IAP.getAvailablePurchases()
      if (subscriptionPurchase) {
        await this.processReceipt(subscriptionPurchase.transactionReceipt);
      } else {
        await this.store.dispatch(user.actions.revokeProSubscription());
      }
    }
  }

processReceipt() sends the receipt to the server to check if the subscription is still active.

If anyone is using Laravel, this seems to be the best package that handles all of the server notifications and receipt validation stuff: https://github.com/imdhemy/laravel-in-app-purchases
