Does anyone have any details about when/if Finnish is coming to duolingo? Thanks if you are able to tell me anything.
Unfortunately, we won't know anything until it's actually added to the incubator. Which might be tomorrow or several years from now.
Have you already taken a look for learning Finnish at Mondly (or Memrise)?
