Swedish "Strengthen Skills" not working on iPhone.
Hi - I'm running iOS 8.2 on an iPhone 4S. Recently, "Strengthen Skills" has stopped working in Swedish. When I choose the weak skill and then hit "Strengthen", I get the message "Could not connect to Duolingo. Try starting the session again." New lessons work fine. I've tried deleting and reinstalling the app, to no avail. Is anyone else experiencing this?
