I am implementing this plugin and setting up notifications such that whenever the SLA is breached, it sends notification. I tried different options like sending notification to "assignee", some fixed email address, or to custom field which contains JIRA user, but none of those send notifications.
I can see that the SLA is breached as the widget turns red and shows overdue, but I didn't receive any notification email. I am trying this by setting SLA time of 1 minute and notification to be sent at 0m prior. I also tried another SLA with time of 7 minutes and notification to be sent at 0m prior. I also tried setting longer duration for SLA and waited few days but still no notifications are sent out. I can send screenshots of my setup if that helps to someone in support individually.
Thanks,
