Posting doubts in comment section of a problem in live contest

I used the comment feature for the “MATHBUZZ” problem to clarify my few doubts about the problem statement. It has already been 2-3 hours since then but still, I haven’t received any reply and now I am not sure whether it was the right method for asking doubts or not. Can anyone suggest, which is the best method to get doubts about live contest problems cleared?

That’s the best method. Wait little more
