If a card still looks old

Apps keep a preview for a while after they first fetch it. These refetch this link:

• SlackSlack keeps a preview for about 30 minutes and won't expand the same link twice in one conversation within an hour. Deleting the first message clears it, or add ?v=2 to the end of the link.
• MessagesThe phone that sends the link builds the card, and the card travels with the message, so a sent one never changes. Add ?v=2 to the link to build a fresh one.
• WhatsAppThe sending phone builds the card and can keep it, failures included, for about a week. Add ?v=2 to the link to build a fresh one.
• XX keeps a card for about seven days and has no refresh tool. Share the link with ?v=2 on the end.
• LinkedInThe Post Inspector refetches the page for new posts. Posts already up keep their old card.Open the tool
• Facebook and MessengerMeta's Sharing Debugger refetches the page when you press Scrape Again. It asks you to log in to Facebook.Open the tool
• AnywhereOpenGraph.xyz fetches the page the way a preview bot does and shows each platform's card.Open the tool
