"Magst du kein Bier?"
According to Duolingo the correct solutions are: Don't you like any eer? or Do you not like beer?
So there is a typo in the correct answer. I wrote: "Don't you like any beer?". But Duolingo website thinks the right answer is "Don't you like any eer?".
My suggestion, and i think it is very important, that you guys review your beta languages with your specialists and so stop this from happening.
