iOS sandbox receipt validation is failing.

Dear PlayFab community,

I am having some trouble with validating a Sandbox iOS receipt using Unity IAP and iOS.

The iOS event that's triggered when attempting to validate is:

I have triple-checked that I'm using the correct BundleID in PlayFab, and that it corresponds to the ProductID for the IAP on iTunesConnect. My test user successfully completed the purchase on the device.

I am not having the same issues on Android with Google Play:

My C# code to manage the Unity IAP aspects is as follows:

Product product = args.purchasedProduct; // args is of type PurchaseEventArgs and is passed into the function.

if ((product != null) && (product.hasReceipt))
{
   /*
   Get the embedded receipt data.

   Example of args.purchasedProduct.receipt:

I have successfully made purchases with iOS in sandbox mode before. As far as I know, this code hasn't changed since I was successful.

I'd appreciate any help anyone can provide!
