I reinstalled the app and now there is something wrong with my "Tanimachi(Premium Member) registration information"

When you reinstall the app after you have once uninstalled or factory reset your device, you will have to go through the following procedures to restore your Tanimachi membership status.

*Add your favorite Rikishi to Gohiiki once again after restoring Tanimachi.
