Firstly, I know this is a non-standard setup, and mostly this hasn't bothered me that much, just more of an inconvenience that any time I've searched for the issue, I could never find it. I think it's hard to explain, so I uploaded a YouTube video.
.
3 Monitors A, B, and C
A - 3440x1440 Ultrawide top left
B - 3456x2234 (Scaling as 1728x1117) MBP screen off to the right
C - 1920x1080 portable monitor below A.
So if the Dock is on the MBP or Monitor B, I can only move it to the portable monitor on the bottom of the arrangement. Now once it is there , it will allow me to get it to monitor A by moving my mouse to the bottom right of the screen (bottom right so I can hit the bottom of the screen without going to monitor C)
MacOS Version - 14.2 (23C64)
Some settings screenshots and a diagram(also attached).
If nothing else a bug report to Apple.
