Hello @khangood,
It looks like it’s not specificaly related to the selected theme, but to the fact that the animations CSS isn’t always bundled in the page with Twenty-Twenty-Three (but it could do this on other themes too). Actually, it’s style-coblocks-1.css (which is CoBlocks main CSS file) that is missing. We will need to ensure that the animation CSS is always bundled, like we already do with the coblocks-animation.js file.
I don’t have an ETA for this fix right now, but one quick solution would be to ensure there’s always a CoBlocks block in your page so all the styles are loaded.
For exemple, if you only add paragraphs (Core blocks), you will see animations in the editor because animation CSS is always bundled in the editor, but not on your site, bacause the page isn’t using CoBlocks’ blocks and thus the required styles are missing. Once you add a Shape Divider (you can set it to 0px height) it will enqueue style-coblocks-1.css in your page and you should now see the animation.
