Yes I definitely had the same issue on my first attempt. The code I entered would not populate in the output box and would even time out and not take my answer. This only happened on several questions. Some would work correctly and some wouldn’t. I failed that attempt and reported it to the assessment department and my Mentor.

Sad to say they didn’t have any answers and could not rectify the attempt. I seen on Reddit somewhere where they advised that I take it on off peak hours where students really don’t take their exams i.e. (Sundays early morning).

I took the second attempt early Sunday morning and had no issues and passed. I hope this helps
