Hi, I’ve just added additional card metadata tags to the FT Video pages.
These add a large display image in twitter:image, a twitter:card:stream property and twitter:card:stream:content_type.
You can see an example page here:
These changes aren’t showing up when the links are tweeted, because the cache is retained for roughly a week, as documented.
However, if you follow the steps to bust the cache, as given here:
They don’t work. I’ve tweeted the page url, then shortened it on bit.ly, then tweeted that shortened url, and refreshed the browser at each step.
But the twitter card still shows up with a small image, and the stream and content type still aren’t picked up by the validator.
Why is this? Do these steps no longer work?
