For sync animations I do the following:
1- import audio
2- go to sync animations tab
3- click on the sync animations during the audio track to animate my slides
4- click on stop sync when it is over
5- click on the small play button to review and make sure all is in its place
When I save and close to return to the presentation - and I do preview or publish to confirm the final result all syncs are delayed (they are no longer like I saw when I hit the play button).
Can you tell me how to resolve this?
