French Possess.2 won't strengthen
No matter how many times I practice Possess.2 in French without any mistakes, it won't turn gold. It's very frustrating.
On the bright side, my understanding of possessives is now rock solid! ;-)
Is anyone experiencing something similar? Is there a fix? I've tried using Duo on my computer through a browser, but mostly do my work through the mobile app.
Grateful for advice or, if this is a bug (and it seems to be), a timeline for a fix.
If you have tried all of these, wait for technical support. I made a couple of mistakes and then I redid with no mistakes. There are two lessons if they both need to be renewed then it can take twice with no mistakes, but it did turn gold for me afterwards. Now, since I did make a couple of mistakes I might have to regild it again later. Even if you make no mistakes, eventually the program will want you to review it for spaced repetition to maintain your memory of it. http://duolingo.wikia.com/wiki/Troubleshooting You can also reach them through the help button on the bottom of the page: Scroll all the way down: https://www.duolingo.com/help
I have the same problem. This seems to be a general problem with the strengthen feature and vocabulary—some words are not listed in the vocab, and therefore continue appearing under strengthen no matter how much you strengthen them. For example, the word cadeau in the French tree.
The best way I found to get around it for now has been to go to the mobile app, check the weakest words (this doesn't appear on the website) and then redo the relevant lessons (as opposed to strengthen), as others have suggested.
