Thanks for the video.
I would like to point out that View the submissions here link in the submission issue is still wrong in the video, and it only takes you to the submissions page if available. This is true in the case of the MDX track and you can see your scores, but for the CDX there is no submissions page, and we cannot see the scores unless we manually correct the URL or have improved our score, which case the leaderboard reflects the score.
If you click on the link in the issue for submission to the CDX track, it takes you to a blank page.
This issue has been raised multiple times by several participants, and I would have expected it to be fixed by now.
