Is there a particular reason this game does not show up if you search the name "Hitman 3", and it only shows up if you search the URL "Hitman_3"?

https://www.speedrun.com/hitman_3

Is this a common problem with new games?

Edit: The game shows up if you type another space after, like "Hitman 3 " Very strange.

seems fine

Maybe it’s only an issue with mobile. I’m experiencing the same thing as the OP.

Update. Works fine for me now as well, maybe just a browser cache error for me,

Works for me now too.
