Moved this discussion to the DPS forums.
Are you using the OAM file or a HTML overlay that links to the .html that edge spits out?
I've found when that happens the best course of action is to archive the folio and download the whole thing again.
I have tried it with OAM File and HTML overlay with the same results.
I started to add item to item and found that when I put some SVG I created that was the problem. As I have texts were created directly in Edge and there's no problem with the animation.
I tried several times to download and archive and did not solve the problem.
Thanks for your replies
