Hi Chinmoyee,

When they go to their assignments page, they will need to click on the "Past" tab (rather than the "Active" tab) to view assignments that are past the due date.

If they are missing assignments, please verify that the assignments are still assigned to them. e.g. If you edited an assignment to change the due date and accidentally removed them from the assignment list, they will no longer see the assignment. You can verify this by editing the assignment and making sure the box next to their name is checked in the students dropdown.

If they're still experiencing issues with this, please submit a support ticket and we'd be happy to further investigate the problem! Please be sure to include the usernames of each of the students who are missing assignments as well as an example of which assignment they are missing.

I hope this helps! Please let me know if you have any additional questions!
