Site is http://www.zoomingo.com/.
When I plug it into the “Validate & Apply” tab at https://dev.twitter.com/docs/cards/validation/validator, I see “*.zoomingo.com approved!” above the Standard Tags section, and all of the tags listed under Mobile App Integration are green. However, I don’t see an option to request approval for an App Card, and when I send out a test tweet linking to to http://www.zoomingo.com/, it shows only a summary card (on desktop) or nothing at all (on mobile).
What am I doing wrong? Is it because my personal Twitter account (this one) isn’t listed as the site owner for zoomingo.com?
