I did observe this connected on VPN (on my laptop) to our vPOC labs. Customer, also on his laptop above when connected to VPN to their environment. Customer also reports its not working even if remote desktop to a server local to his environment and run PS locally (still on VPN when connecting to the server though).
I have not tried that myself or had the chance to connect to a system on corp net (without VPN).
Ideas welcome, I want to show off the new stuff when demoing and this sorts of break that. 😉
