How do I make a loading screen for a browser game?

construct.net/en/tutorials/how-to-use-loader-layouts-to-make-custom-loading-screens-9

for some reason this tutorial does not work for me, something additional I have to do?

I'm trying to made a browser game but this tutorial is not working for me.

Is your project large enough to need a loader screen? You might just be downloading fast enough to skip it, or your game is already cached.

I opened an old project to prove what you said,and you're right ^^
