In-App Purchase Restore - No observers found

When I execute a restore on my in-app purchase I'm getting a warning, however the restore is successfully executed. I think this is something new with Xcode 14.3. My test device is running iOS 16.4

This is the warning: <SKPaymentQueue: 0x283708a80>: No observers found that respond to "paymentQueue:shouldAddStorePayment:forProduct:", will not check for purchase intents

It fires at this point in the code. If I comment out the first line, I don't get the warning however, the restore doesn't execute. Is anybody else seeing this or do I have something wrong in my code? I know it's only a warning but any help would be appreciated.

@IBAction func restoreButtonTapped(_ sender: UIBarButtonItem)
{
        SKPaymentQueue.default().add(self)
        SKPaymentQueue.default().restoreCompletedTransactions()
}

I've included the rest of the code just for a completeness.

func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction])
    {
        for transaction in transactions
        {
            switch transaction.transactionState
            {
            case .purchasing:
                //print("Purchase in progress...")
                break
                
            case .purchased:
                //print("Purchase Successful")
                
                SKPaymentQueue.default().finishTransaction(transaction)
                //print("Transaction Complete")
                
		// Hide the restore button
                navigationItem.setRightBarButton(nil, animated: true)
                
                //Set the BaseVerion in the Db to true
                IAPHandler.set_BaseVersion_To_Purchased()
                
                //Also hide the Purchase button
                UIView.animate(withDuration: 1.0, animations: { [weak self] in
                    self?.purchaseButton.alpha = 0
                }) { [weak self] (success) in
                    self?.selector_Top_Constraint.constant = 30
                }
                
            case .failed:
                if let error = transaction.error
                {
                    let errorDescription = error.localizedDescription
                    print("Transaction failed due to error: \(errorDescription)")
                }
                
            case .restored:
                
                SKPaymentQueue.default().finishTransaction(transaction)
                //print("Transaction Complete")
                
		// Hide the restore button
                navigationItem.setRightBarButton(nil, animated: true)
                
                // Set the BaseVerion in the Db to true
                IAPHandler.set_BaseVersion_To_Purchased()
                
                // Also hide the Purchase button
                UIView.animate(withDuration: 1.0, animations: { [weak self] in
                    self?.purchaseButton.alpha = 0
                }) { [weak self] (success) in
                    self?.selector_Top_Constraint.constant = 30
                }
                
            case .deferred:
                //print("Purchase Deferred")
                break
                
            @unknown default:
                if let error = transaction.error
                {
                    let errorDescription = error.localizedDescription
                    print("Transaction failed due to error: \(errorDescription)")
                }
                break
            }
        }
