This is setup to send to the Activity Assignees, 0 hours before a Scheduled Phone Call activity. It is enabled, and has a simple email message.
Under Scheduled Jobs, I can see that "Send Scheduled Reminders" (Job.send_reminder) is enabled, is running always, and the logs say it is successful.
If I then create an Activity of type Phone Call, set its status to Scheduled, set the time to 30min in the future, and assign it to myself, I will immediately get a system generated Activity Summary email. In 30min time I will not get a reminder from the Scheduled Reminder, with the template I defined.
Can anyone tell me why, or tell me where to look for more information? Are there logs which will show me if the reminder is actually being triggered, or if an attempt is made to send the email?
