Why are goal notifications not delivered?
When configuring tasks on the Setup and Maintenance work area, if you disable notifications for participants, then they won't be notified.
In BPM Worklist, search for and select the GoalNotificationFyi task. On the Assignees subtab of the Task Configuration tab, click the Goal Management FYI Routing Participants node. On the Advanced tab, if the Ignore Participant check box is selected, participants won't receive notifications.
