Definitely not a bug. they wouldn’t have put one control in control center for it if it was intended to be space selectableThanks, during the keynote I remember them specifically saying that it would remember window location, so hopefully that's just a beta bug, and hopefully that means turning stage manager for one space is just a bug.
It take Apple several OSes to allow different spaces for different monitors, and allowing for screen for just one monitor. I remember when making an app full screen, it would blank out my other monitor. 🤞
