From within a course, if I hit the three dots next to a lesson, I can hit “Save”. Yet, nothing seems to happen. No visual confirmation of any kind. When I later switch my internet connection off, I can’t access the lesson. Maybe I am doing something wrong?
The course in question is a really long epub (LingQ split it into about 500 lessons, I believe), in case that’s relevant. But I am not trying to save the whole course, just individual lessons (though the whole course would be pretty useful too)
