Remote Desktop Multiple Monitors

Hi - Mac M1 with an external monitor and using Optimize for Retina Displays when RDP into Windows 11.  When keeping the M1 as the main monitor works fine the optimize for retina. I've made a Mac Studio Display the main monitor and the M1 the extended, and now when using optimize for retina resolution appears to be off in RDP session - can't find icons, two blank screens.  I don't think it has to do specifically to the Studio Display as it did it also with a regular Dell second monitor.  Seems like something about making the external monitor the "main" monitor ruins it.
