Stage Manager opening apps on both external monitors at the same time
When using the Stage Manager and "Displays have separate Spaces", and two external monitors, I can have an application open on (lets say) the righthand-side monitor (for example, Google Chrome). When I bring a different app to the foreground on the lefthand-side monitor (say the Finder), if I have the Finder also open in the background of the righthand-side monitor, the system opens the Finder app windows to the foreground on BOTH monitors. I don't want to affect anything in the foreground of the righthand-side monitor, when I'm bring new apps to the foreground of the lefthand-side monitor. Can I adjust a setting to avoid this behavior? Thanks!
