Skill strengthening seem very broken, buggy, not working

Skill strengthening is not strengthening skills and is asking the same questions over and over. Both for timed practice and untimed. Been doing it for days now. Seems to be broken for strengthening specific skills and well as general strengthening.

Having to redo lessons to strengthen skills.

This is in Esperanto

=============== EDIT =========== It had returned to working right for a while but has now stopped working again on March 11 2016.

To add a little aggravation, while wasting time on non-working strengthening, several other skills lost their all gold status, meaning I'm losing skills while correctly answering skill strengthening questions.

========EDIT AGAIN ======== So far redoing the first lesson seems to be making ones with only one gray bar be all gold again, not needing to redo all of them. I don't know that applies consistently.

Yes, it is very annoying. I did like five or six timed-practice-repetitions (about 100 XP) on the skill "Occupation" in Dutch - it did not progress and kept asking me the same questions over and over. I had this problem once on the iPad app and thought it was an issue with the app, but two days ago it also happened on the website.

I'm having the same problem with French. It worked fine earlier today, but now it suddenly has stopped strengthening my skills no matter how many times I go through a lesson. Restarting Chrome doesn't seem to have any effect for me.

I've noticed that when I get a question wrong, it repeats the question and then when I get it right, it repeats it again. Probably a bug but I'm not sure.

Skills won't strengthen if you didn't do well in a lesson, that may be the problem (If you did good, then it's probably a bug)

Yes, I have been seeing this issue for several days now in Russian and in Dutch. Closing and relaunching Chrome seems to fix it, but it is still very annoying.

I already had that last year. Very annoying. Because after some time I need to strengthen 1000+ words, if it works again.

For me it is only really broken since today. Before I had only 15 words I could not strengthen because they never showed up. Today I get the same lessons... You may need to know that I try to keep all words at full strength, I am not focused on the tree itself, but on the words page.

I have the same problem in the Italian tree (I haven't tried Russian yet), it is very annoying. I hope they fix it soon!

I'm having the same problem with the French tree. I'm trying to strengthen individual skills as I normally do, but even when I get every question right, it doesn't strengthen it. Trying the same skill again gives me all the same questions I just did. I'm not using timed practice, just regular, if that matters.

ETA: I just restarted Firefox and logged out of and back into Duolingo, and it worked again for one lesson but then stopped again...

It's working right again. I had already cleared cache and cookies and used different browsers and such so I don't really think my actions made it start working but it can't hurt to try clearing your cache and cookies if you're using a client that allows that.

I have the same problem in the Spanish for English speakers tree. Does the staff monitor forums to know how many of us are having this problem?

It stopped working. I was using Duolingo at midnight, so maybe crossing a date and resetting from PM to AM has to do with it. I tried logging out, clearing cache and cookies, but now luck.

This is a SERIOUS problem. There's nothing to do in Duolingo, gamewise, on a completed tree other than strengthen skills and take the overall test. Having to completely redo every non-gold course to get the only reward left, all gold strengths, as if you hadn't taken them at all, is a low return in satisfaction for the effort.

5 hours after posting this reply, it's working right again.

I'm frequently getting this problem on the Esperanto course, specifically for the 'Dates/Time' skill. If I strengthen the skill and get every question correct, it still doesn't turn gold.
