Polish is out on iOS!
If you use iOS, you may want to check the updates for your Duolingo app – yesterday's update introduced Polish into the app!
Please note that the fact that Polish is here was not mentioned in the patch notes, so it may not be final yet. But for now, it's there and it seems to work just fine :)
If you don't want to wait for the official update, you can try this: 1. Select Polish language on the website 2. Open your Duolingo app 3. Ignore the message about Polish being not supported and tap on the background behind the message (it's easier in landscape mode)
But I guess you won't need this since apparently the official update for Android in on the way.
