I have my domain whitelisted, my tags set up using yoast seo and it works perfectly fine in the validator.
INFO: Page fetched successfully
INFO: 22 metatags were found
INFO: twitter:card = summary_large_image tag found
INFO: Card loaded successfully
I have also tried other plugins but with no avail. I furthermore have created a robots.txt file with the following to see if that would work.
However no card shows up for me. Please Help!
