are you requesting the published content? If yes you will need to pay attention to the cv parameter which is required when working with it. The value of the cv (cache version) parameter needs to be changed so that the new content can be fetched from the server instead of getting the old content from the CDN.
This is a typical request for getting the published content: https://api.storyblok.com/v1/cdn/stories/home?version=published&token=5EgKInxYa31dIBnLS3UrSQtt&cv=1595529854
