Thanks again for flagging this and sorry for the trouble. We dug into it and figured out what happened.
A couple of lessons in that course had been temporarily removed by the original sharer, then added back. Because of that timing, your completion percentage was being calculated against the full lesson set, including the lessons that weren’t actually visible to you at the time, so you couldn’t hit 100% no matter how many lessons you finished.
The lessons should be visible to you again now. If you open the course, you should see one or two incomplete lessons left. Here’s a direct link to one of them: https://www.lingq.com/en/learn/fr/web/reader/41475392
Once you finish those, you should be at 100% and the challenge should reflect that.
Let me know if anything still looks off and we’ll sort it out.
Sorry for posting again. I seem to have the same problem - this time with a Ukrainian book «Україна. Історія. Орест Скбтельний». I read the whole book, but the challenge says it was only 86.67%.
I’m not seeing any previously removed lessons with this course. Can you see any lessons that don’t have 0 next to the words count? No titles? Very sorry about this.
I have 13 Lessons in this course. I shows 0% near all of the lessons. There are also no new words. I have just clicked through all of them one again. In the past this sometimes helped, but not this time. It still says that I am at 86.67% completion.
Do you have any other ideas what I could do - apart from giving up and choosing a new book.
I really like this challenge, but I am disappointed how often it does not work properly and it does not show that the book was finished, even so I have read everything.
See my post on Feb 3. I have many books tagged. Last time I looked, I didn’t get credit for them. I don’t even know where to look now. The first link has a weird 404 error message.
