Hello @chinma. The professors use a tool which helps track all assignment posts. When I tried, I wasn't able to find your post. We have already identified a bug which might have caused this to happen. Could you please explain the things that you did after creating the initial post. Looking at your blockchain history, I can see that there were 3 separate edits made on your main post. Did you by any chance hit the delete button after your post was created? This is just so that I understand the bug better to be able to probably fix it.
