Based on what I see at: https://schools.duolingo.com/ I think I'm missing something when I use my dashboard. I cannot see very much information about my students and their progress. Even when I click on them individually I cannot find the graphs alluded to in the site linked above. Am I missing something or is that feature forthcoming?
I think the functionality is not there yet. there is only one "PC" version, as it's a web app. However, sometimes duolingo experiments with users, giving a part of the users e different version. nothing you can do about this though.
