How to edit UI on Mobile But not on PC?

TRying to make it so That the UI is bigger on PC then on moblie. I think there is a way to do it because I have seen games with UI different of both.

This is called UI Scaling. You could research on this by searching “UI Scaling” on the devforum or on your web browser.

You could use Ui scaling plugin and then go into device emulated and change to any device and test it out!
