Someone else said it doesn't work. So you need to have Discord COMPLETELY CLOSED if you're playing this, not even running in the background LMAO.
Probably one of those weird things technology does. You know, how some things work for others while some don't. Then you turn off a completely unrelated setting and suddenly it starts working. Computers are weird like that. Code, is weird like that.
I still think it's better to be safe than sorry though, and keep Discord OFF on the off chance the setting decides to just stop working.
