As you can see in this picture, when I use RoyaleAPI on my computer, the ads on the side block the deck refine tool and I can’t use it. I can’t exit the ad by clicking the X either. This is only specific to computer.
edit: the image isn’t loading, but basically the left most ad covers the gamemode sidebar, so the only way to access the different gamemodes is by scrolling down enough that they appear over the ad.
