The Prodcut Card page (https://dev.twitter.com/docs/cards/types/product-card) says that “This Card type requires special approval, and is not available for immediate approval at this time.”.
We got our Product Type approved quite quickly though, which is great.
But it’s not showing properly in the tweets we tried.
Here is one page having meta tags inserted and prpoperly showing in the preview tool (http://www.reunion.fr/modules/fiche-etablissement/etablissement/1056-le-relais-des-cimes.html).
Have we done anything wrong?
