New UI: timed practice

[stfods]

Hi,

Sometimes in timed practice "continue" button disappear and you can't continue to the next question after submitting an answer to the previous one. Keyboard shortcut doesn't work as well.
In such state practice ends when timer runs out.
env: Windows 7; latest Firefox, new UI

Thanks in advance,

I have the same problem - Windows 7, Latest Chrome, new DuoLingo UI. For me, it doesn't let me continue after answering the first question at all. I tried everything.
