Does World Composition work on mobile?

Is World Composition working on mobile? I’ve changed position for some sub-levels and it’s working on PC but not on Mobile Preview.

I would like to generate some level using World Composition but it need to work on mobile…

BTW it’s working on New Editor Window, but it isn’t in Standalone Game as well :confused:

EDIT: Well I needed to Save All and it’s working now.

From OP: “Well I needed to Save All and it’s working now.”
