On my MacBook, I'm running a Windows VM using Parallels. I'm trying to set the MacBook's built-in screen as the primary display for the VM, but it's not allowing me to do so

After upgrading to Parallels version 26.0.1, I encountered an issue with display priority in my Windows VM. When only one external monitor is connected, the MacBook's built-in screen can be set as the main display. However, once two external monitors are connected, the built-in screen is no longer selectable as the main display within the Windows VM.

I am currently using three monitors. When I try to set a different monitor as the main monitor, it does not switch properly. Also, the monitor size is detected incorrectly, causing menu operations to not work. After applying the settings and rebooting, sometimes the main monitor is set correctly, so for now I am using it after rebooting. However, when I want to change the order of the other monitors to 2 or 3, the change does not apply properly.

Same issue here. I can somehow use both monitors Macbook Pro M3's display and external one that I have used on the machine since 2024. They work flawlessly on Mac mode. They work in Coherence mode but Coherence after the 26.01 upgrade seems glitchy and still not at all in Windows 11. Many thanks
