Perhaps I am confused also. I do run the cron job every 15 minutes, but the whole point of the digest format is that it only goes out once per day. How can I force it to go out now, even though it would normally wait until tonight so that I can debug it?
That works, but at least as of 3.9.x, you can't set 0 - this won't work. You must use ie. "1". See kernel/classes/notification/eznotificationcollectionitem.php:
