We are having an issue with post dates; when we update an article, it doesn’t show the updated date. Instead it pulls the old date published. Even so the dynamic post date was set to “Modified only,” but still it doesn’t show.
Are you using the theme’s default post meta, or did you build it using a Block Element? The method to adjust it will be different depending on which approach you’re using.
If you can share one of the posts, I’d be happy to check.
