Hi,
I have updated the status of the order in this way:

$order = wc_get_order($orderId);
if ($order) {
    $order->update_status($newOrderStatus, '(by cron)');
}

or

$order = new WC_Order($orderId);
if ($order) {
    $order->update_status($newOrderStatus, '(by cron)');
}

This code has updated the status but email does not sends.

Please advise.
