Assignments automatically completed
Hi there! I started using Duolingo with my students last week and to ease them into it, I gave them two assignments: - gain 50 XP - complete a specific lesson
The first one worked as intended, most students have completed it and I can track their progress.
However, as soon as the students clicked on the specific lesson, it marks it as 'complete' for any student.
How can I fix this problem/avoid this situation?
