I think learners would benefit from the immersion section. Is it coming soon?
As much as I'd love to have it here, Norwegian will likely never have an Immersion section.
Duolingo staff has stated that Immersion takes too much resources compared to the relatively low increase in user engagement that it provides, and that they have no commitment to rolling it out for the new language courses. Source.
Keep in mind that the vast majority of users are app users, who have no idea Immersion even exists.
