Calling fetchItems twice doesn't work in a single app session

[fdbk-web]

Nativescript versions @nativescript/payments 1.0.4 @nativescript/core: ~8.1.1 @nativescript/ios: 8.2.2

iOS Version: 15.1.1

Device: iPhone 13 Pro max

Summary of issue: First time calling .connect() and fetchItems is fine. Subscriptions and IAPs (app store products) etc. load. Second time we call it in our app, it does not load at all. However, restarting the app seems to load the app store products again.

We used the code structure provided in this plugin documentation.

Workaround/fix for now: Call teardown() before you leave the subscriptions/IAP page, etc.

eg.

import {
  buyItem,
  BuyItemOptions,
  canMakePayments,
  fetchItems,
  finalizeOrder,
  init as initPayments,
  Item,
  PaymentEvent,
  paymentEvents,
  toMainThread,
  tearDown as cleanUp
} from '@nativescript/payments';

onClose() {
    // Clean up what we've done here as otherwise subscriptions won't load on 2nd reload
    cleanUp();

    this.location.back();
}

Suggested course of action: Update the docs for this plugin to make it clear that tearDown should be called before leaving the page with the subscription / IAP options, etc.

Screenshots: When everything is fine (1st call / call with the fix above):
