ProductID on iOS uses this value.

I think I am using product id from proper place. Is not that place? I have problem to localize place from your printscreen. What is path to there? Is not product id from particular subscription or in app purchase?

[pulmuone]

The reason is that “Status = Ready To Submit”. It has not yet been approved by Apple.

[dbdariusz]

But I am doing test on TestFlight. For that purpose I think I do not need to submit. Am I correct?

It has nothing to do with the status of your app's TestFlight and subscription information.
Even if it's TestFlight, your subscription information must be marked as "Approved."

If you tell me your email address, I will send you a video of my settings screen.

Are you saying to test app via TestFlight my subscription must be approved? Is there a way to test payments with sandbox account when status is not approved?

Your subscription settings must be approved by Apple.

I also have this issue, but I was told by apple team that first you must test them and then submit app for aproval. I still haven't managed to get the product to display. Have you managed to get them loaded in test flight?

I have app available in test flight but I cannot test there subscription. Based on pulmuone subscription must be first approved by Apple.
I am not sure yet if if there is a way to approve subscription without approving distribution itself. Is there? If no, that will be tricky to ask Apple to review app with subscription which were not tested in TestFlight. Am I missing something? How to send subscription to review?

you must sign the Paid Applications Agreement.
go to AppStoreConnect -> Businees

I have the same issue. Seems plugin is not able to pick up an in-app purchase until its approved by Apple. But in order to Approve I should initiate a new distribution which is always failing their review due to non functioning payment page

I'm also observing the same. I only have created one in-app purchase for testing purposes. I get the "Invalid products found when querying product list" when trying to do a PurchaseAsync and when I try to do a GetProductInfoAsync.

The purchase is a consumable.

My code is simple.

try
{
    var connected = await billing.ConnectAsync();
    if (!connected)
    {
        //Couldn't connect
        return;
    }

    var productInfo = await billing.GetProductInfoAsync(ItemType.InAppPurchaseConsumable, "Test1_InAppPurchase_ProductID");

    // Test ConsumePurchase
    var purchase = await billing.PurchaseAsync("Test1_InAppPurchase_ProductID", ItemType.InAppPurchaseConsumable);

    if (purchase == null)
    {
        // did not purchase
        return;
    }
    else if (purchase.State == PurchaseState.Purchased)
    {
        var wasConsumed = await billing.ConsumePurchaseAsync(purchase.ProductId, purchase.TransactionIdentifier);

        if (wasConsumed)
        {
            // Purchase was consumed
            System.Diagnostics.Debug.WriteLine("Purchase was consumed");
        }
        else
        {
            // Purchase was not consumed
            System.Diagnostics.Debug.WriteLine("Purchase was not consumed");
        }
    }

}
catch (Exception ex)
{
    //Something has gone wrong
    System.Diagnostics.Debug.WriteLine("Error - " + ex.Message);
}
finally
{
    await billing.DisconnectAsync();
}
