Order status update with note doesn’t send email?

Order status update with note doesn’t send email?

I can do something like this:

$order->add_order_note( $order_note, $is_customer_note );
// Update order status.
if ( $order_shipped ) {
$order->update_status( WC_ShipStation_Integration::$shipped_status  );

Customer will receive 2 emails: an order completed email AND a separate email with the order note.

When I try to combine this

$order->update_status( WC_ShipStation_Integration::$shipped_status, $order_note);

In the admin, I can see the order status set to completed, and the order note (both separate). But no emails sent.

I want to send out a “completed” email with the order note attached, instead of 2 different emails.
