Chiming in to also say I'm getting the multi-monitor issue.
Prior to today, SAB worked fine.
Now, with SAB enabled, and taskbar set to "Show on Main Monitor", enhanced taskbar shows on secondary monitor (monitor 2). When hitting Windows Key on keyboard start menu pops up on secondary monitor. Behavior is same regardless as to which monitor is selected as 'main' in windows settings.
If I disable SAB, default windows taskbar works correctly.
My secondary monitor is a TV that I keep off most of the day, so not being able to see the start menu is rough!
Will update here if i find a workaround; but assistance appreciated!
I'm on latest version of SAB, and Windows 11 is up to date.
