I’m trying to preview my card data to make sure it’s right using the preview ability on this page: https://dev.twitter.com/docs/cards/preview
The URL I am trying to use is: http://joshholat.beta.mirrorgram.com/photo/14 (still in the very early testing stages )
It keeps saying:
“Looks like something is technically wrong.
Please try again in a few minutes.”
Does that mean my card data isn’t right or something is actually broken with the previewer?
