Yes, we do have some problem with displaying the results. Currently, all submitted solutions were correctly evaluated but their score in not visible on the leaderboard. We are working on it... I very sorry for the inconvenience.
I'm glad to let you know that the problem was fixed :-) Thanks for your patience!
I got score = 0, so is it still some problem?
Actually, after some time, score changed from 0 to other value ...
