Twitter card whitelist rejected almost immediately.
The email says : “The URL you provided for clee.zappfactory.co.za to use the summary_large_image card did not validate. Please make sure the page contains valid metadata, then reapply for a Twitter card.”
But the card validator found the following:
INFO: Page fetched successfully
INFO: 13 metatags were found
INFO: twitter:card = summary_large_image tag found
WARN: Not whitelisted
What am I missing?
