JIRA does not send notifications for Custom Events

[Eric Bergeron]

Hello Atlassian Community, 
I'm struggling with email notifications from Custom Events. 

I've followed all these steps: 
https://support.atlassian.com/jira-cloud-administration/docs/configure-email-notifications-for-a-custom-event/

And made sure to select a Template (tried both the Issue Assigned and the Generic Event template): 
https://confluence.atlassian.com/jirakb/jira-does-not-send-notifications-for-custom-events-771895197.html

However no one is receiving any notifications. The notification scheme has custom events, which are configured to notify a project role. Also tried a Group, and a single user (current user). 

I'd love to get this fixed!

(Alternatively, if there's a way to notify a specific project role or group, when a new issue hits a QUEUE, that would also work. I've only found outdated or Server-related Atlassian community articles.)
