Also another thing, how do I close the PC app? There is no way to actually close it down.

Update: Yeah there is a nasty big X there that I can finally enjoy closing. Props to finally fixing the bug with ending a race. Amount of times I had to Alt+F4 over the last couple of years just to reopen the game for stream. But loads of work to do!
