I have an audio-streaming site written primarily in PHP. I have dynamic meta tags in place which populate v well in WhatsApp and Facebook. Whilst currently i am not using the official twitter:card markups, i am using og: image which is a documented fallback.
I have inputted various URLs into the card validator and keep getting
INFO: Page fetched successfully
INFO: 11 metatags were found
WARN: Not whitelisted
I have no further options or indicators to proceed. Do i need to submit a request for my site to be whitelisted? If so - how? The validator is obviously picking up the metatags…
Thanks in advance for any advice
