how can go to next level :(
"I exited the app, came back, and now it is refreshed and fixed. ;)" The same i did but nothing and i restarted my phone. My problem was, probably, that i changed my profile name on my pc but the phone did not synchronized. I pressed disconnect and i logged again. Now it works. Sorry for my english. I'm only on 'Food and Animals'
Hi, I had the same issue. The Basics lessons are comprised of several lessons with each one. I felt kind of silly but after trying and trying to unlock the next session, I came to the realization I hadn't finished all the lessons in Basics 2. Go back into Basics 2 and make sure you have finished every lesson within Basics 2.
