It's finally been added XD

1st place can be the fruit crown, 2nd place can be the gold trophy, 3rd place can be the silver trophy, and 4th place can be the bronze trophy. Dis sound cool?

I am unable to find anything about what difficulty we need to play on mobile

It appears you have it so that the three first levels are categories with each level inside of them. This means that each level has three separate leaderboards, which obviously isn't how it's supposed to be.

I think there should be a category for levels 1-3, for people who haven't bought the full game. A level leaderboard would also be cool.

I think there should be an Xbox category because Xbox is the only console that I'm able to record it on
