My and my friend's Duolingo iOS apps have different contents in the same course

We both learn French course on our iOS apps, but our icons for each lesson are different. And in the "Adjectives 2", there are 10 lessons in my app but 11 in his.

Why is that?

Probably an A/B test (some people are placed into test groups but not everyone), or one of you needs to allow your app to update.

Thanks for your answer. Both of our apps are up to date.
