Quick challenge perk

Question

Hello! First time creating a post here. I don't know if this was posted before or not, but I've found an interesting way to challenge people. Wait for the challenge opponent screen to load. Half a second after pressing Random Opponent, just press back and you'll be able to press the button again. Quick way to fill the 20 challenge count!
But its kinda spammy, so use it with care :)
