So I've got a U3421WE which is being used with both a desktop PC via DP and an 14" M1 Macbook Pro via USB-C.  Everything works properly on the mac side, I can assign a keyboard shortcuts via the input manager tab of DDM and have it toggle over to my PC.

The issue is on the PC side. No matter what I set the input switch shortcut key to in the DDM input manager, nothing works. The keyboard shortcuts do not work at all. Has anyone else experienced this? I've got the latest firmware on the monitor and the latest version of DDM / Windows 11. Is this a known issue with Windows 11 and DDM? I've scoured the internet for an answer but haven't found this exact issue discussed.
