In my Phone I can play Standard, Chess960, Custom setup and Key Position but on my PC I can only pick Standard and Chess960.
I have looking at 100+ Youtube videos that try to show how to do it but non of them works and most of them are just clickbait that show a Phone screen.

Wonder why they did hide it like this on the PC and not have it as in the App...
