Is there a way of notifying the Cards crawler to reindex a card’s metadata if, for an example, the image changes?
Same question. It would be nice if https://dev.twitter.com/docs/cards/getting-started page explicitly specified if there is a way to request crawler to reindex page. So far the page only says “Your content is cached by Twitter for 7 days after a link to your page with card markup has been published in a tweet” which is somewhat helpful
Any updates on this question?
No, the current best information on attempting to “force” a cache refresh is still the information on the cards troubleshooting page in the documentation.
