Question Submission Errors
Resolved - Beginning December 1, some students encountered errors when attempting to submit answers. Clearing cache and cookies resolved the issue for many multiple-choice questions, while some algorithmic questions continued to trigger errors. Our engineering team investigated and deployed a fix, and the issue was fully resolved as of 4:00 AM ET this morning.

No further impact is expected. Additional updates will be posted here if needed.

Aktiv Assignment Loading and Submission Issues
Resolved - Starting Friday afternoon, students reported that Aktiv assignments were not loading and were instead seeing a consistent error message across multiple courses. Only assignments that were currently active or due were impacted; past-due assignments continued to load normally.

Throughout the weekend, additional issues were identified related to assignment visibility and question rendering. These included:

- Students being unable to scroll through their assignments to view all questions.
- Certain numeric-entry questions displaying broken LaTeX in student view, rendering the question unreadable despite appearing correctly in instructor view.
- Intermittent messages stating that submissions could not be completed. Although this message appeared for some users, the underlying submissions were saved and graded correctly.

All issues identified between Friday and Sunday have now been fully resolved. Assignments are loading as expected, all questions render properly, and student submissions are being recorded and displayed accurately.

If you continue to experience any unexpected behavior, please get in touch with our Support team.

LaTeX Display Issue
Resolved - Between November 25 and November 30, some questions containing LaTeX did not display correctly or failed to appear for students. This issue has now been fully resolved.

Ungraded questions and newly added questions will display properly going forward. To protect existing student data, questions that had already been graded prior to the fix were not modified.
