can't access (unlock?) level 3 stories???
Spanish, Duolingo, Windows 7. Guess I didn't realize how extensive this site is.
I figured it out and the levels are now unlocked. The problem is that, although some of the stories APPEAR to be finished, they are not. What is very confusing is that they title the last story in level 3 something like "Camping, Part 1". The first story in Level 4 is entitles "Camping Part 2". So you finish "Camping, Part 1". and think you should be going to "Camping, Part 2" in Level 4. But the "Camping, Part 1" story actually has multiple parts, so you need to finish all those first before Level 4 will unlock. Hope this helps
