Hi George,
Thank you so much for reaching out! I’d gladly love to assist.
It looks like in the code it is missing calling the fetchContent function from within useEffect() hook. I’ve linked a CodeSandbox link with a working React integration for reference: https://codesandbox.io/s/builder-react-integrating-pages-2-kp19hb?file=/ src/App.js:0-1220
Please let me know if this helps. If this doesn’t work, please share a link to your content and we can take a further look.
Thanks.
