@Andrew,
The situation where the lesson pages' ID is displayed in the browser's URL is with those settings:
lesson settings: Display Default Feedback NO
question: all Answer Responses are empty
Workaround so that URL does not display lesson ID and page ID in browser:
- either enter a Response (feedback message) in your questions' Response fields (from a pedagogic point of view, I feel that all Answers should have a matching Response (feedback message) attached, so that the student knows why they got their answer right (or wrong)
- or set lesson settings: Display Default Feedback YES
