Are you sure that Crop is the way to go? Because it doesn't really seem to work out well for me.
Also, where do I find the Viewport and Anchor? Are these system expressions or a configuration options?
Viewport system expressions
Anchor —/pin/bullet

Viewport is the only way you can make your game fit all of drvice/screen
Make your UI likethis
Set button.width=viewportright(0)>viewportbottom(0)?viewportright(0)/10:viewportright(0)/5
Set button.x=viewportright(0)>viewportbottom(0)?viewportright(0)/10:viewportright(0)/5
Then your game will fit mobile and PC
