is it just when you make a build that it stops working?

I only ask cause it seems to be working for me in editor but the build settings aren’t all setup.

So here is what I see when I play.

So all working there, but if you make a build you can see that the menu scene isn’t in the scene list.

So you should just have to delete the sameple scene from that list and add menu as the top item. Should get you going.
