Hello, this is Black Survival.
Starting from 10:07 AM (GMT+9) today, there were few reports on the issue of logging in and connecting Black Survival to STEAM platform.
As of 3:00 PM (GMT+9), we have grasped the authentication error by STEAM has been resolved, hence, we are currently inquiring STEAM to identify the root of the cause.
Once again, we deeply apologize for the inconvenience caused.
