Bug Information

Plugin.InAppBilling.InAppBillingImplementation.PurchaseAsync(String productId, ItemType itemType, String obfuscatedAccountId, String obfuscatedProfileId)

https://github.com/jamesmontemagno/InAppBillingPlugin/blob/ac395d86e03e7c62d26338624449099960332cb3/src/Plugin.InAppBilling/InAppBilling.apple.cs#L318

Opportunities for nulls in this function are:

SKPaymentTransaction obtained on line 321 may be null
The SKPaymentTransaction object obtained on line 321 may have a null value for TransactionDate: https://developer.apple.com/documentation/storekit/skpaymenttransaction

But it's not clear to me when these would occur.

Version Number of Plugin: v6.6.2.1 Device Tested On: iPhone XR, iOS 13.3 Simulator Tested On: n/a Version of VS: 17.5.4 Version of MAUI: 7.0.86

Steps to reproduce the Behavior

Expected Behavior

No NullReferenceException

Actual Behavior

NullReferenceException
