Can't use Firefly beta

Hello! Maybe I don't understand something about using the Firefly but can't get access to the line to witch the prompt request needs to be entered/

By clicking on button "Generate" on main page, i go here https://firefly.adobe.com/inspire/images# and see only login suggestion under the video. After clicking "Sign in" and entering login and password happens nothind, I see same page again with video and login button.

By clicking other options on main page i get same result: heading (text), video and login form, for examle, here https://firefly.adobe.com/generate/font-styles

Thanks for attention
