Discuss sentence button not working
Hi, I know this has been discussed before but I can't find it: when I hit the "discuss sentence" after putting in my answer, nothing happens to the screen. How can I "activate" this to see what people are saying, thanks?
This problem isn't specific to any one course. It's actually an issue on Duolingo's side. Unfortunately, there's nothing you can do to fix it or 'activate' the button.
Personally, as in your case, I think, when you couldn't open the "discuss sentence" button, you can choose Discussion tab next to Activity tab. Then, at Discussion stream, you can see the "Search" box, type the sentence that you want to leave your comment in here. Duolingo Search will show you all results match with what you typed, included the name of the forum it belongs to, choose which discussion you want.
