hello guys i have just given codeforces round 974. I had registered for the contest 3-4 hours in advance.Now after the contest ended, i went to my profile to see my contest rankings but it is showing that i have participated as an unrated participant in this round. I am not sure what to do. I am a beginner at this platform,so i dont know what have i done wrong while registering to become an unrated contestant. please help me
