Hi davince koyo,
thanks for reaching out to us.

We just tested the issue mentioned by you and it seems to work just fine on our end. Please delete cache & cookies and try again (or use a different browser). Further, you can simply click on the next lesson (on the left side panel), since the previous lesson is finished when all quizzes are completed and you are free to move on (previous topics should be crossed out). Hope this helps!
