How do you go from subtopic 1 back to the Topic and THEN to subtopic 2?
Prezi Next is not designed to move that way. By default, it goes from Topic 1 to subtopic 1, 2, 3, then back to the overview. You can override this using the back arrow at the bottom of the screen when presenting. If you want to change the sequence without using the back arrow, you can use zoom areas instead of topics. This gives you control over the movement of your prezi. Read the details in my article Use Zoom Areas to Make a Prezi Next Path
