I've updated the Remote Desktop app to version 10.7.6.
Copy-And-Paste seems to be broken in this version.
The host is a macbook pro running macOS 12.3. Guest is a windows server 2012 R2.
I can paste content from guest-to-host but not from host-to-guest.
I've downgraded the app using Time Machine to a previous version ( 10.7.2 (1965)) and the Bi-Directional Copy and Paste works again.
This is a show-stopper, so please fix this!
