Hello there, Thank you for reaching out. We understand a weekly challenge didn't register your progress. We're sorry to hear of this, as we can imagine how this would cause concern. So we can effectively investigate, please consider providing us with screenshots or a short video which illustrates what you describe. An image of the impacted challenge itself would be helpful. You can upload any screenshots or footage you record to a media-hosting site such as Imgur or Youtube, and share a link here. We'll then review.
