SAT Cancelled - How To Reschedule?

We received notice today that my son’s SAT was cancelled for August 29th. On the SAT Twitter page it said you can log in and look for alternate test sites. However, when you log in it says the registration deadline was yesterday and won’t even let us look at other sites. Any one else have this problem? Are we doing something wrong?

You’re probably doing everything right. Did you try selecting a new date? 8/29 cancellations are happening all over. It’s highly unlikely you can get another seat on that date.
