I failed to complete social media account authentication.
If the message "Authentication was not successful" appears when you attempt to use "Back-Up Data with SNS", one of the following may be the cause:
1. There is already play data linked to your social media account.
*You must unlink the pre-existing play data from your social media account before proceeding.
2. You have entered your social media account ID or password incorrectly.
3. Service to your social media account is currently unavailable.
*If you encounter the issues in numbers 2 and 3, please contact the relevant social media provider for support.
