Duolingo started fun for my children but the numerous updates have caused them lots of stress and upset. One of my children completely lost their streak with an update then they were jumped back several units. Meanwhile my other child was jumped ahead and couldn't keep up. The addition of goals went from one quest to multiple quests and with being jumped around on the units, it all ended in lots of tears and just not worth the stress. Therefore all 3 of my kids have slipped away from what was initially lots of fun and lots of learning. It is impossible to contact Duolingo for support also. I wouldn't recommend this anymore.
