BUG: Progress not recorded
I was on Duolingo on this account yesterday, but my points were not recorded, and my streak time was reset to 0.
This happens to me as well… specifically for Adverbs on both the iPhone and online (noted since they are two different methods of progress).
It's been only nine months since I reported this. You have to give them some time. :)
After further searching, I found another thread that indicated it is an interface issue. (Here: https://www.duolingo.com/comment/207144)
When I used Duolingo in Chrome, the one skill that would not improve moved to gold at last. So I asked this question about getting it to work in my iPhone: https://www.duolingo.com/comment/6495552
