A suprising bug in iOS App: Jumping between languages
I got this very surprising bug on the iOS app of DL. I was doing german course, when I tapped the next lesson to continue, the content suddenly changed into a French lesson, which I had never reached in my French course. I completed that french lesson and the program showed I have completed a part of french skill I had never activated. But it only flashed for a second and then everything went back to normal.
