Microsoft Remote Desktop multi screen Issue for M1 MacBook Pro

Thank you mpgny  and John_Spencer 

Thanks mpgny for helping out. As mentioned, developers are aware of this issue and working towards a fix (multiple Tech Community threads tracking it), I will re-open the ticket to signify this! gfpcp 

My IT department had Microsoft Support observe my computer and took notes. We tried a horizontal arrangement of the screens and that worked. It was when one monitor was placed beneath the other two that causes the app to fail. They said they were aware of this particular bug and would be building it into a future release. Probably not 10.7.8 but after that. 

In the mean time there appear to be two work arounds, downgrade the app if you have access to an older version, such as 10.7.1 or arrange the screens side by side. 

I don't know if there are other bugs that might be at work in your situation, but that appears to be the one I am wrestling with. Best wishes. 

Anyone knows how to re-open this ticket, it shows as closed and i'm not sure Pernille-Eskebo will do anything about it.

This is happening on 16" MacBook Pro M1 Max, when connected to 2 extended monitors and starting a remote session to a Windows machine. The remote session will only use 1 monitor with low resolution. The only solution I have now is like mpgny  to remain on an old Beta version 10.7.1 . Would love to see it fixed in a newer release, so I can update the application.

My IT department help me downgrade to 10.7.1 and the feature was restored. I am thankful. This is a really important feature to me. 

I have the same problem again as before like gfpcp and mpgny. MB Pro 14" 2021 with M1, RDP 10.7.7. When I have "Use all monitors" checked, it will open just on one monitor. When Resolution is setup to "Default for this display" it opens in small rectangle with resolution very similar to my old calculator 😄 .(640x480 or something similar)

same issue as gfpcp . 

16" MPB Pro M1 Max with 10.7.7 RDP will not engage multiple local monitors when connecting to VM running Windows 10. 

This issue seems to have reappeared over the weekend; any updates rolled out? I am on  version 10.7.7 on a 16" MBP M1

10.7.5 in App Store has fixed this problem
