Hello Twitter team,
I had posted this on a previous thread titled “ERROR: Required meta tag missing (twitter:app:swift:name)” but i have not received a reply.
We facing the same issue while trying to validate the twitter card. The url which has the metatags is, http://playfolly.com/play
The app id’s are specified correctly on the metatags but we still get the following log when trying to validate,
INFO: Page fetched successfully
INFO: 22 metatags were found
INFO: twitter:card = app tag found
WARN: Not whitelisted
ERROR: Required meta tag missing (twitter:app:swift:name)
It would be great if you can help.
