How to detect if leaderboard is activated for a player?

On mobile devices, leaderboards doesn't show. I'd like to know if leaderboards isn't showing so i can give the player access to a custom leaderboard that can be closed so it doesn't cover the screen all the time

1, Leaderboards should normally be showing on mobile, I'm unsure why they arent

2, Rather than seeing if the leaderboard is not on the screen, wouldn't you just want to see if the player is on mobile?

3, If you want to know how to detect if a player is on mobile, there is an existing article on how to detect players on mobile: Scripting Helpers Question #64592
