Does not work. To replicate this simply follow the tutorial/steps outlined above.
This was tested with two standard iClone characters and two iPhone 12 pros on the same WiFi network. Both phones and live face apps connected successfully in iClone but only the data from the first phone connected is being used.
I might add that both phones and live face apps work independently, just not when used together as two live face gear inputs in motion live. So there is no issue in connection or firewall unless something funky happens because both send on port 999. I haven't found a way to change the port number though and the screenshot in the official documentation clearly shows two live face inputs using the same port as well.
