Square Enix has announced that it is ending support for the iOS version of Final Fantasy Crystal Chronicles Remastered due to a change in the version’s in-app purchase model.
Back on January 24, players reported that they couldn’t access their paid additional content in the iOS version of the game. The issue impacted both the free and fully paid versions of the game on iOS.
When Square Enix investigated the issue, it figured out that changes to the in-app purchase model caused it. However, Square Enix concluded that it could not completely fix the bug while simultaneously implement the new changes. As a result, Square Enix has decided to completely cease service of Final Fantasy Crystal Chronicles Remastered on iOS.
