In the 3-31-2018 Release Notes, it was mentioned that a new last_attend_at obejct was added to the Enrollments API.
Last Attended At Enrollment Object
The Enrollments API returns the last_attended_at parameter for an enrollment object.
When I query the Enrollments API, I can see this object, but it's perpetually NULL. I've tried about everything I can think of to have a student participate in a course, including using Roll Call to take attendance, but I cannot get this object to update to anything other than NULL.
Does anyone else know anything about this new parameter, and how it's expected to be used?
