Twitterbot not redirecting through og:url


#1

Hi, we are using an og:url to a canonical landing page which holds our metadata. While testing through multiple social sites, Twitter doesn’t redirect to that url and therefore cannot see all of our metadata. Using the card validator, I get this following output:
INFO: Page fetched successfully
INFO: 6 metatags were found
WARN: Not whitelisted

When pasting into Twitter, no metadata is shown.

Please advise.
