I made changes to the description and meta field bundling and other contents in the background, but none of them were displayed on the foreground page
Hi @hcx 
The description and the metafields behave quite differently on the storefront, so a few details would help narrow this down.
What’s the expected behavior versus what you’re actually seeing? A clear before and after for the description, the metafields, and the bundling content is useful, since they each render in their own way.
Can you also share the exact steps to reproduce it, from making the edit through to viewing the page where it should appear? It’s worth confirming whether the change was made on your published theme or a draft, and whether a hard refresh or an incognito window changes anything.
Are you editing in the admin or through the API? If it’s the API, paste the request and response, including the relevant headers, so we can confirm the call is succeeding and the values are saving as expected.
One thing worth checking on the metafields specifically. They don’t appear on the storefront automatically, the theme template has to be connected to the metafield through a dynamic source in the theme editor or referenced directly in Liquid. If that connection isn’t set up, a populated metafield just won’t render. There’s a good walkthrough in displaying metafields on your online store.
