Accidental Dutch exercise on mobile phones?
Yesterday I practiced my Dutch tree at my home PC and left. A few minutes ago I tried to practice Spanish via the Android app and found myself in a Dutch exercise, probably redirected from my yesterday practice at home. I was surprised because I knew Dutch wasn't available for mobile devices yet. Still, I was able to finish the exercise. After that, the app kept telling me Dutch wasn't available on mobile devices yet and redirected me to Spanish.
What's the matter?
