I have been learning Japanese. Now I'm stuck because the hints are missing or wrong, I can't learn when I can't get a clear picture of the sentence structure. Audio is missing. Once you get to the greetings lessons and beyond, even a few before, the app goes downhill. Duolingo does not teach us as children that know little to nothing, but throws us under the bus thinking we know structure of sentences, vocabulary, and other things that make the language clear. The grammar is incorrect.
