The Pokémon Company have announced that the service for the smartphone game Pokémon Duel will end on october 31, 2019. Sales of paid items, such as Gems, have ended. You will be able to spend Gems you already possess until the end of the service. For any player who has purchased the Player Pass, the Player Pass will not be renewed any further. Once these services have ended, you will no longer be able to install or update the game or transfer your account. Additionally, if you already have the game installed, you will not be able to continue to use the app except for certain functions.
