Hey @Ilya Basin ,
On macOS, certain key combinations (such as Command + Space, Control + Space, and other system-defined shortcuts) are intercepted by the operating system before applications receive keyboard input. This behavior is enforced by macOS to ensure system-wide accessibility, input source switching, and security features.
Because the Windows App operates as a standard macOS application within Apple’s event-handling framework, it cannot override or capture these globally reserved shortcuts. As a result, some key combinations may not be forwarded to the remote Windows session, even when the app is running in full-screen mode.
As a workaround, you may reassign or disable conflicting macOS shortcuts (for example, input source switching) in System Settings → Keyboard → Keyboard Shortcuts, or use third-party key-remapping tools if appropriate.
If you still wish to share feedback, you can share the feedback on Windows App itself about the same.
On Windows OS, it has the feedback button here (left-bottom side);
