How can I add another recipient to the form submission notifications?

Hi there, I have been able to add a second email address to the form submission notification but the test email only sends to the email associated with this account? Regardless if I also remove that. Please can you advise how I can ensure the second email address is added and go about sending a test mail to it?

I assumed you already know how to add multiple recipients, just in case you need a quick guide here's the link: Sending notifications to multiple recipients

The problem is that  you are using the Test Email button which only sends notification to the email address you signed up. In order to fully test multiple email notification, please open your actual form and fill it up then submit it.
