Refreshing a cached preview

Platforms cache preview cards. After you change a card, a link that was already shared may keep its old preview for a while.

• Facebook and Instagram: paste the link into Facebook’s Sharing Debugger and press “Scrape again”.
• LinkedIn: use the Post Inspector.
• X: the card refreshes on its own within a few days; a new slug refreshes immediately.
• WhatsApp and Telegram: cached per chat; a fresh share in a new chat shows the new card.

For a campaign that must look right from the first share, set the card before sharing the link anywhere.
