Thumbnail not updated on Facebook. What should I do?

I’ve changed the thumbnail of my booking page, but when I try to share it on Facebook, it still shows the old image and description.

Step-by-step guide:

1. Go to the Facebook Sharing Debugger
2. Copy and paste the link to the debugger.
3. Click on the “Debug” button.
4. Click on the “Scrape again” button.
5. Share your booking page on Facebook (after scraping again, your thumbnail will be updated automatically).
