Where is my Standard Task?

Q: Why is my Standard Task not showing in the drop-down menu?

A: The Standard Task will not be an option in the drop-down unless it has been assigned to the selected property.

Setup --> Task Rules, Edit Assignments (people icon)

Hint: In order for Standard Tasks to appear in the drop-down menu, the Task Rule must be task type Standard Single Task, and it must be assigned as an option to the appropriate properties.
