Pokémon GO Tour: Kanto bonus event

Trainers, Due to a technical issue that occurred during Pokémon GO Tour: Kanto, some Trainers were able to access the ticketed portion of the event without purchasing a ticket. We apologize for this issue, and to help Trainers who purchased a ticket feel like they are receiving its value, paid ticket holders will be able to participate in a bonus event.
