Saving Work on Lessons
I don't know why this topic hasn't gotten more attention.I would imagine lots of users would run into this problem on their mobile devices. Maybe there is more discussion on this subject under another post.
I use the iOS version of Duolingo (for French). Given my schedule I often have to stop in the midst of an exercise and resume it later. Unfortunately, I often loose all of the work I did. Duolingo aborts the exercise — probably because of memory or a time-out "feature." I would really appreciate an option to save an exercise so I can stop it and resume it later. If duolingo can't program it to do this automatically, then provide us with an option to save our work at a given point in time and then return to it.
