As players celebrate the release of the new mini-set in Pokemon TCG Pocket, some are being locked out by an infamous error code that has persisted since the game’s global launch. Although it has never been this prominent, it now seems like one in every ten players is encountering an Authentication Error when trying to open packs or log into the game. On December 17, the devs issued an Update Notice addressing known issues with the Amber Trainer Card acquisition but did not mention the login error messages affecting players worldwide.
