At least they now seem to know about the no login issue. Instead of an endless loop to the login screen, they're now adding a pink box that says, "Our system is having trouble. Please try again or come back later." Gee, that's a big help. In the meantime neither my wife nor I can log in at all.
And now, at 1:18 Central, two minutes later, it appears to be fixed. They were out for 20 minutes or so.
