iPad Keyboard Doesn't Work - Double Hop

I feel like this used to work before 12.1.  Here's the details.  I'm on an iPad Pro with the magic keyboard or whatever it's called.  I use an RDP app on the iPad to RDP into my office machine which is a Windows 10 machine.  The keyboard functions flawlessly with this connection.  I then launch a Mini Remote Control Session from my Windows 10 Machine to another machine on my network.  That MRC session does not register the keystrokes from the iPad.  Anyone have any ideas on how to fix this?  I feel like it used to work, but cannot say that for certain.
