I had a PPTX project with narration and quizzes that worked OK. I had to add some slides and then re-narrated. I think I managed to link the quizzes to the new project, but they do not execute when the timeline gets to them.
My recollection of v.8 is that it was easier to insert previously designed quizzes.
I'm pretty sure these are timeline quizzes and not media quizzes.
Any help is appreciated.
