Card Validator: "Warn: Not Whitelisted"

[Fortinet]

I am getting a warning about whitelisting and would really appreciate some feedback.
My domain is https://www.fortinet.com

From what I can gather from other threads, this is a common issue and someone on the Twitter side has to manually whitelist. Can someone please advise?

That’s not the case at all. Please check our pinned troubleshooting post for all of the things you should check. Your homepage certainly doesn’t seem to have any twitter:card markup.
