You just joined. It does not appear that you have any puzzle rush scores.
Were you talking about appearing on the leaderboard for Puzzle Rush for 3 minute, 5 minute or survival?
I haven't heard that you have to be approved to be on one of the leaderboards.
Long story short, a while ago chess.com started making it a requirement to be "approved" in order to qualify for above 50 puzzle rush scores to appear on the leaderboard. These approved people generally being titled players but I also see untitled all the time.
I get it, people cheat on puzzles, so this is done to protect people who got such scores with honest work.
I messaged chess.com support a while ago after getting a score above 50 but they did not tell me how to get approved, they just made me aware of this and I researched further on the chess.com forums without finding an answer. Is there a way? Since then, I get a score above 50 regularly but my high score does not show on the leaderboard and sometimes doesn't even register on my profile.
So at the same time it's, disrespectful to people who want to be on the leaderboard and do not cheat. Chess.com has not made it clear on the future plans with this.
