Update social media preview cards

When you share a Medium post on social media, a card is created with a preview of your content.

Social media websites such as Twitter, Facebook, and LinkedIn look at the initial post data, including your title and featured image. If you make changes to those elements, Medium sends out the new information. It might take some time for those services to update your preview card data, but you can use their tools to force them to update your data right away.
