The ICPC 2021 Online Round hosted by Amrita University is going to be held on July 10th, 2021, which is the same date Codeforces is hosting Round 731. So, if there's an option to prepone or postpone the round, I would request the problem-setters to please look into the situation. I guess no-one wants to miss either a Codeforces round or the preliminary ICPC round.

Don't know the problem-setters yet, so tagging MikeMirzayanov
