Duolingo just went nuts on me
I had to use google translate to get to file this request/complaint. So I load up Duolingo on my mobile, and it abruptly takes me to a page with all different languages. I press "back" and it somehow decides to delete my previous language trees and reset my account to study English as a Dutch (?) speaker. I go onto my desktop, and sure enough, it doesn't even show an English interface any more. All my languages appear gone. I don't even know how to switch the language back, the entire interface is in Dutch. Wtf?
To everyone asking how I got my account back: I went to the desktop version (the website) and eyeballed my way to the languages selection menu, and selected "Learn Spanish from English" (which was my main language, but I suppose you can just select the main language you were learning & learning from). That brought back the English interface and the from-English language tree. Then I went and deleted the Dutch language (from the settings). (Duolingo support, you can show up at any time now since this is ridiculous).
Never mind, I found the problem (and it's very, very stupid). I added the Norwegian course on my desktop. The Duolingo mobile app got confused, since Norwegian is desktop-only for now, and hence said I have an "unauthorized language" or something like that, and for some reason reset to "Learning English from Dutch". Took me a while to get my account back as it was, and the problem still happens if I try to use the mobile app. This is stupid and should be fixed.
Here's the official answer from the Duolingo.com help center:
At the top of the page, mouse-over the language you're incorrectly "learning" (which is probably English). Then click on the bottom selection, which is supposed to be "Add a new course". See this image for context: http://i.imgur.com/eH7D8dY.png (Since I've since changed my settings, I can't do much in the way of screenshots for you, unfortunately.)
When you get there, choose what language you speak from the pull-down menu at the top right ("Engels"), then choose what language you want to learn. For me, this was Spanish ("Spaans", I believe, but you should be able to recognize it from the graphic).
