UniFi Alerts Not Working For Disconnections

Since late June/early July my UniFi controller is no longer sending disconnection alerts. I noticed the “Notifications” tab is missing from classic settings so I went to the new user interface settings and couldn’t find an alert option for Disconnections. Anyone have any thoughts on how to get them working again?

SMTP settings are fine as I can receive all test emails. Need to figure out in particular how to get the disconnected devices alerts working again.
