U3824DW, multiple PCs, 3rd device not working
I'm "upgrading" from the U3818DW where I had 3 devices working using the built-in KVM. Great! Now that I have upgraded, I cannot get the 3rd device to work over the KVM. Why not? This seems like a huge downgrade to me, and makes me regret getting the new version. Outside of buying 3rd party KVM, how can I get the 3rd device working?

MacBook Pro - USB-C 1
Mac Mini - USB-C 2/HDMI 1
Windows (RTX 3080) - ???/HDMI 2
First 2 work great.

@Monitor Mayhem
In the current setup, what happens if you open the Menu- Input Source and check/select HDMI 2? Does the Windows PC then appear onscreen?
Swap the Mac Mini and Windows HDMI. Do you then "lose" the Mac Mini on HDMI 2?

The monitors/HDMI work between all 3 devices. I can switch with no problem. It's the connected mouse and keyboard that don't work.

The only work around I see is before switching to Windows PC, disconnect the USB-A to USB-C cable from the Mac Mini USB-A port and connect the USB-A end to the Windows PC USB-A, then Input Source switch to HDMI 2 and see if the mouse and keyboard work.
