If you've canceled the Player Pass but the subscription is still active, you cannot purchase the Player Pass.
In addition, if you attempt to repurchase the Player Pass from a new copy of the Pokémon Duel app using an Apple ID from which you have previously purchased the Player Pass, you will be unable to purchase the Player Pass even if you canceled your Player Pass from your previous copy of the Pokémon Duel app and your membership became invalid.
This is due to the specifications of the Apple App Store and does not affect Google Play or the Amazon Appstore.
