I've taken a long break from Duolingo, but when I came back today, I find that I can't make any progress on any level. I've tried numerous times and when I click to finish, it takes me back to the home page and it doesn't register. Any ideas?
Same thing is happening to me. I've done the first italian lesson 4 times now and no progress is recorded.
Yeah, I'm having this problem too. For me the progress is only recorded maybe one out of every three times. I think I read in another thread somewhere that this is due to the servers being too busy, because the website getting lots of extra traffic recently. Pretty annoying :(
