Animate Classroom In a Book Ch. 5 Problem

Hi All,

We are working in Ch. 5- the particular part we need help with is Adding Motion Guides for Classic Tweens.  I'm a newbie at Animate as well, so I haven't been able to pinpoint our issue.  When we add the fly as a symbol- We don't have any trouble adding the guides until we exit out of symbol editing mode. When we double click on the fly to enter back into symbol editing mode, the fly does as expected- it moves on the created path.  But after the symbol is moved onto the main timeline, it doesn't move at all. What step are we missing?

TIA!
