Pokémon Sun & Moon - Friendly Competitions
Following the announcement of the glitch with Friendly Competitions on Friday, The Pokémon Company has now put out a note saying that the glitch hitting the Friendly Competitions, where it'd block users from participation if they scan the QR Code before the competition, has now been resolved and should no longer have that effect.
