Is the Course part of a Curriculum?
Thanks for replying Jorma.
No, this particular course is not part of a curriculum.
We do have curriculums set up for other courses and all of the same members enrolled in that curriculum. The reports for that curriculum work fine, despite having the same user group.
Well, that takes my silver bullet. You will likely need to reach out to Adobe to verify that there isn't an issue in the data base or with the reporting function of that course.
The reason I asked about the curriculum is that the course won't show reports for users enrolled through a curriculum. You can only access the reports through the curriculum reporting functions.
