In the Andriod application all the languages have fluency level except Japanese, why?
I don't think that the course needs it anyways. Japanese is such a vast language and Duolingo barely covers the surface. The 'fluency level' would just be depressing seeing it so low, even after completing the tree.
The web version doesn't show the fluency score yet either.
I would like to see the fluency score added for the Japanese course too, even if they are as completely meaningless as people always say. (I'm supposedly 59% fluent in English—according to the JA→EN course—even though I'm from England, haha.)
