No immersion or words learned in menu bar??
So I got my other half joined up to learn German and I noticed he had extra things on his menu. Is this a dutch or a platform thing?
Dutch is not an in-house built course. It is one of the courses built via the incubator and incubator courses do not have the words or the immersion feature. This is because Duolingo does not believe these features have priority (based on statistical research they have conducted) and they would rather spend manpower on improving the site in ways that statistically show to improve users' retention, user numbers and course success.
If you're looking to practice vocabulary, there are memrise.com courses available. Memrise courses are flashcard based and our Duolingo course vocab has been included in one if not several courses.
