Expected Behavior

That we will receive the lastest inAppBillingPurchase

Actual Behavior

• it will trigger an exeption in the purchase flow, with a PurchaseError.GeneralError error, and the message "7"

Code snippet

the request code 7 triggers an exception that prevent some of the internal code from being called. I think.
public static void HandleActivityResult(int requestCode, Result resultCode, Intent data)
{

        if (PURCHASE_REQUEST_CODE != requestCode || data == null)
        {
            return;
        }

        int responseCode = data.GetIntExtra(RESPONSE_CODE, 0);

        switch (responseCode)
        {
            case 0:
                //Reponse returned OK
                var purchaseData = data.GetStringExtra(RESPONSE_IAP_DATA);
                var dataSignature = data.GetStringExtra(RESPONSE_IAP_DATA_SIGNATURE);

                tcsPurchase?.TrySetResult(new PurchaseResponse
                {
                    PurchaseData = purchaseData,
                    DataSignature = dataSignature
                });
                break;
            case RESPONSE_CODE_RESULT_USER_CANCELED:
                tcsPurchase.SetException(new InAppBillingPurchaseException(PurchaseError.UserCancelled));
                break;
            case RESPONSE_CODE_RESULT_SERVICE_UNAVAILABLE:
                tcsPurchase.SetException(new InAppBillingPurchaseException(PurchaseError.ServiceUnavailable));
                break;
            default: // ----------------------HERE---------------------------
                tcsPurchase.SetException(new InAppBillingPurchaseException(PurchaseError.GeneralError, responseCode.ToString()));
                break;
        }
    }

The code in InAppBillingImplementation on Android: async Task PurchaseAsync, never gets to the case 7, so never returns the purchase.
