FWIW I've had that same hangup before.

As I clicked just now, I see that "jump" page in the address bar, but it was quickly overtaken by the normal page.

Clicking refresh or stop and refresh, didn't change it for you? That always helped me before.

Also, if you didn't clear anything before going directly to the site, I wonder if it still could have gotten your attempt and made it possible for you to still get credit. Maybe possibly, depends, I suppose.
