An unfixable bug has led to Final Fantasy Crystal Chronicles Remastered being pulled from the iOS store. The in-app purchase mechanic saw some changes, which led to the bug.
On Twitter (via VGC), the iOS version of the game is going out of service. In a blog post, it stated that only those who did in-app purchases from January 2024 and onward are applicable for refunds. If that sounds like you, you should contact its support team by August 31, 2025.
The bug people were facing before the closure basically refuses to let specifically iOS users access DLC content they paid for. From the sound of it, Square Enix did attempt to fix it, but weren’t able to, so the version is down and unlikely to return.
As it stands, Final Fantasy Crystal Chronicles Remastered is still available for PS4, Nintendo Switch, and Android.
