Copy and Paste not working while Remote Desktop Manager is running
One other interesting thing is that I noticed when I have Remote Desktop Manager open, I get a Microsoft Office clipboard error. This error only appears when I have RDM open and have logged into an RDP session. In this situation, I was attempting to copy and paste data within an Excel worksheet on my local machine.

Hi, It's currently set to Legacy.

Copy and Paste not working while Remote Desktop Manager is running
Copy and Paste isn't working for me while Remote Desktop Manager is running.
I can't copy and paste on my local machine, or between RDP sessions.
As soon as I quit the application, local copy and paste works again.
I'm on Windows 10 20H2 and Remote Desktop Manager Free 2021.1.17.0
