Handy workaround for Stories
I'm learning German from French, so stories aren't available like in German from English. I accidentally found a way to do German stories from English and keep my German from French tree.
I got into stories from a language that has them (French from English), then changed my learning language with the drop down tab. Duo asked which language I want to use stories for, and I chose German. After completing a story, I even got points.
I just thought this would be good to know for people learning a language with stories available, but from a language other than English.
I discovered an other trick, if you're on a computer, reduce the window of your navigator until you see a book appear down. Then click on it and you have access to the stories. Please don't fix it it's handy.
