After Creating a private contest, I tried to add my problem in Polygon to Codeforces but failed. So I have created a new contest in Polygon and added the problem "example-a-plus-b*" only. However, I can't add this problem as well. So I want to know what should I do in this case.↵

Additionally, I have added "codeforces" as a reader.↵
