New words in the Android app requested before shown once.
My brother installed the application just yesterday. In a few German lessons, it has started to grow incresingly obvious that you are often required to type in new words ("Translate: cheese") or even write down whole sentences with them read by a TTS engine — without even being introduced to these new words.
I also noticed that his order of the lessons in Duolingo differs somewhat from PC and iOS versions. Is something wrong with beginning German skills or the application itself?
