I have a strange problem in 3.9. 2.
For students the checkbox finished assignemt is always on, although they did not hand in the assignment ( completion set to hand in as completed) or received a grade for a quiz ( completion set to receive a grade). As teacher manager I see mine unchecked.
1: new test student... no change
2: different themes
So it seems not to be related to a student or a theme. Any ideas?
