How are you adding those metatags? Are you using Helmet? If so, are you rendering it during server side rendering or are you dynamically rendering it after the page was rendered (for example, based on the state)? Metatags need to be rendered on server so they are part of the page's codebase (check yours here view-source:https://cuteanimalplanet.netlify.app/10-pictures-of-tiny-kittens-youll-want-to-put-in-your-pocket/ and you will see they are not being rendered there).
