Uninstalling the app may not delete the app data on certain Android devices. If this is the case, please follow the steps below to delete the app data.
1- Ensure you have a way to directly add or delete data on your device, such as using an SD card
2- In the SD card or internal storage where the game is saved, open the 'obb' folder inside the 'Android' folder.
3- Delete the folder labelled 'com.square_enix.android_googleplay.dq8j'
The above operation requires you to connect your device to a PC and use an app specifically for managing file data. The setup for this differs for each device, so please refer to your device's user manual for more details.
The game may be stored on the SD card or the device itself depending on the type of device you use.
