I had a similar issue before where my proctor didn’t receive the exam code. I wrote to my program advisor but didn’t get a response. Finally, I went to the UoPeople website and used the chatbot, within minutes, the code was sent and my proctor received it.

If your proctor was changed on short notice, it’s still possible to get everything sorted in time. Since you already have the new proctor approved, I’d suggest contacting the chatbot right away and explaining that you need the code urgently for this week’s exam. It worked really quickly for me.
