Edge Text Effects in Chrome not Working - from Dan Carr / Inspire Mag article

I've been working with the tutorial in the September issue of Adobe Inspire to create text effects with Edge Animate - see link:

I can get it to work well in IE and Firefox but nothing much happens in Chrome.

Anyone any idea where I may be going wrong?

My problem is with the section specifically relating to using Edge Animate - the other parts of the tutorial work OK in Chrome when using a plain HTML file but I'm interested mainly in adding the text effects to existing Edge compositions.
