New Order Emails Not Sending To Multiple Addresses

First, thanks for this great eCommerce platform.

Second, for the new order notification emails to the seller, there are 3 comma-separated email addresses entered. WooCommerce is only emailing the first address.

Any solutions would be GREATLY appreciated!
