I use the custom certificate plugin and it works great. One issue: When I hide and then unhide it, the system emails the certificate of completion to ALL of my students at once so I get hundreds of people who are confused why they are re-receiving their certificates of completion. Is this a bug ? I'd prefer to be able to do various things without the risk of all my students getting re-emailed their certificates that they already got. Thanks in advance.
