iOS subscription expiration

Hi,

I am implementing a subscription feature in an iOS app development project.
Using Unity 2020.3.26f1 and UnityIAP 4.5.1, I am implementing the public PurchaseProcessingResult ProcessPurchase(PurchaseEventArgs args) method.

public PurchaseProcessingResult ProcessPurchase(PurchaseEventArgs args)
{
    Product product = args.purchasedProduct;

    bool isPurchased = false;
    var receipt = args.purchasedProduct.receipt;
    CrossPlatformValidator validator = new CrossPlatformValidator(GooglePlayTangle.Data(), AppleTangle.Data(), Application.identifier);
    IPurchaseReceipt[] purchases = validator.Validate(receipt);
    if (purchases != null)
    {
        foreach (var purchase in purchases)
        {
            AppleInAppPurchaseReceipt appleReceipt = purchase as AppleInAppPurchaseReceipt;
            if (appleReceipt != null
             && DateTime.UtcNow <= appleReceipt.subscriptionExpirationDate)
            {
                Debug.Log("*** purchaseDate:" + appleReceipt.purchaseDate, Debug.Type.Web);
                Debug.Log("*** subscriptionExpirationDate:" + appleReceipt.subscriptionExpirationDate, Debug.Type.Web);
                isPurchased = true;
            }
        }
    }

    if (isPurchased == true)
    {
        SubscriptionManager subscriptionManager = new SubscriptionManager(product, null);
        SubscriptionInfo subscriptionInfo = subscriptionManager.getSubscriptionInfo();

        if (subscriptionInfo.isSubscribed() == Result.True
         && subscriptionInfo.isExpired() == Result.False)
        {
            Debug.Log("*** PurchaseDate: " + subscriptionInfo.getPurchaseDate());
            Debug.Log("*** ExpireDate: " + subscriptionInfo.getExpireDate());
        }
    }

    return PurchaseProcessingResult.Complete;
}

Within this method, I am using SubscriptionManager’s getSubscriptionInfo() to retrieve the SubscriptionInfo and confirm the getExpireDate().

Premise:
The environment is set to Sandbox.
The subscription update frequency is set to “monthly update every 5 minutes.”
Two subscription items are available: 1 month and 3 months.

Steps:

  1. Purchased a 3-month subscription item at 11:00 and confirmed that the expiration date is 11:15.
  2. Attempted to downgrade the subscription by purchasing a 1-month subscription item at 11:05.
    The expected expiration date should be at 11:20, after the 3-month subscription renewal.
    However, the receipt shows the date of 11:10.
    If the environment is Sandbox, will the subscription items “1 month” and “3 months” be parallel?

Thank you.

Hello shimizuzu,

This is an issue with Apple’s Sandbox where the behaviour is different from production and doesn’t support upgrading/downgrading subscriptions. On Sandbox, both will be treated as their own.
