Swapping Battle Backgrounds Live & to Work in Multi Battles

[GameboyLuke]

Hey B)

So recently I've had a lot of success with swapping out the default WiFi battle background with a custom background such as Spear Pillar (from the Alola photo club) or Giovanni's Room in Team Rocket's castle, however... I can't seem to get these battle rooms to work when I initiate a multi battle for a Free-For-All for example. I was wondering if anyone would be willing to help or share potential knowledge on how to overcome this problem. It would be super appreciated.

Thanks :]
