The mark scene as 1st scene is not working correctly it confuses scene the scene I marked as 1st scene isn’t constant sometimes it’s another scene & I always Mark splash screen followed by main menue 1st yet the mechanic does it’s own thing even when I arranged the scene in the particular order I want like previous versions still

When you launch a preview, the currently edited scene is the one that is started.
