Just remember fam: you can use the Windows App on macOS to connect to a Linux RDP session, but you cannot use the Windows App on Windows to connect to a regular Windows RDP session :)
I haven't tried this on Windows yet because it appears to require a Work or School app. I'm really confused as to why you can't connect to a remote PC from Windows with this app? Is this an intentional strategy, or is it "coming later"? It looks like the "metro" version of Remote Desktop Client app is still available in the Windows store, and as long as I can Start -> Run "mstsc", I'm happy. :-)
Also, on macOS they have renamed the Remote Desktop Client to Windows App and it appears to work exactly like the old app. Which is different to how the Windows version of the app works.

Crazy stuff...
