Sandbox test on iPhone are not working

Hi, guys.

I test my IAP functionality on Unity and everything is working perfectly (get data about my items, I can purchase and restore), but when I try it on my iPhone with Sandbox, I don’t even get the information about the item.

I’m using UNITY 2019.3.06, iPhone X, iOS 10, and the IAP package is 1.23.1.

This is my current code:

using System;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Purchasing;

// Placing the Purchaser class in the CompleteProject namespace allows it to interact with ScoreManager,
// one of the existing Survival Shooter scripts.
//namespace CompleteProject
//{
    // Deriving the Purchaser class from IStoreListener enables it to receive messages from Unity Purchasing.
    public class IAPManager : Singleton<IAPManager>, IStoreListener
    {
        private static IStoreController m_StoreController;          // The Unity Purchasing system.
        private static IExtensionProvider m_StoreExtensionProvider; // The store-specific Purchasing subsystems.

        public string NO_ADS = "NO_ADS";

        void Start()
        {
            // If we haven't set up the Unity Purchasing reference
            if (m_StoreController == null)
            {
                // Begin to configure our connection to Purchasing
                InitializePurchasing();
            }
        }

        public void InitializePurchasing()
        {
            // If we have already connected to Purchasing ...
            if (IsInitialized())
            {
                // ... we are done here.
                return;
            }

            // Create a builder, first passing in a suite of Unity provided stores.
            var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());

            // Continue adding the non-consumable product.
            builder.AddProduct(NO_ADS, ProductType.NonConsumable);

            // Kick off the remainder of the set-up with an asynchrounous call, passing the configuration
            // and this class' instance. Expect a response either in OnInitialized or OnInitializeFailed.
            UnityPurchasing.Initialize(this, builder);
        }

        public bool IsInitialized()
        {
            // Only say we are initialized if both the Purchasing references are set.
            return m_StoreController != null && m_StoreExtensionProvider != null;
        }

        public void BuyNoAds()
        {
            // Buy the non-consumable product using its general identifier. Expect a response either
            // through ProcessPurchase or OnPurchaseFailed asynchronously.
            BuyProductID(NO_ADS);
        }

        public string GetProductPriceFromStore(string id)
        {
            if (m_StoreController != null && m_StoreController.products != null)
                return m_StoreController.products.WithID(id).metadata.localizedPriceString;
            else
            {
                Debug.Log("ERROR: Can't find the price of the purchasing product");

            }
        }

                // system's products collection.
                Product product = m_StoreController.products.WithID(productId);

                // If the look up found a product for this device's store and that product is ready to be sold ...
                if (product != null && product.availableToPurchase)

Could you provide the device logs for further investigation?

Don’t worry. I took the option of using the Automatic Generated buttons for IAP that now UNITY has. They work perfectly -at least for the moment-.

I left the link reference for other people.

Glad you got it working
