What is Multi-Login?
This is a feature that allows you to log in to both the mobile version and PC version (Steam) with a single account.
After setting up Multi-Login, various data will be shared, with some exceptions.
You can log in to one PC version (Steam) and one mobile version on separate devices.
This is different from the process of transferring your account to a different device on the mobile version (Link Data Function).
