If you have problems logging in using a Google or Facebook account in the gameNotice
Many websites and apps support Google and Facebook logins. For this function, the login program provided directly by Google or Facebook is executed at the same time. However, this feature cannot be fixed by game developers even if a problem occurs. If Google or Facebook login does not work properly, please use the following method. 1. Turn off your phone and turn it on again. 2. If you are using Google or Facebook app, please update the app. When a problem occurs, it is often resolved in this way. Use this method if you have similar problems with other apps.
