The progress doesn't update
Whenever I do a lesson, it doesn't update the progress and i can't go on with the lesson
The same for me on the web.
I posted about it earlier. https://forum.duolingo.com/comment/32643500
I do a lesson. I don't get xp for the lesson. And when I try to take a lesson in the same skill, it just give me the same lesson over and over.
But good news it did work for me in the app. So I could do the lesson, get xp, and keep my streak.
