"Choose your practice schedule" button not loading (SAT)

I know this was posted already in SAT and Test Prep today, but I wanted to make sure it got seen here as well.

When I try to edit or add a practice schedule in SAT practice, all I get is a loading screen and an exit button. Changing computers, browsers, or wifi networks doesn't resolve the issue, and it doesn't seem to be affected by cookie settings, trackers, or ad blockers. At least three people are having this problem.

My only guess is that it has something to do with this morning's SAT administration.
