Happily I got approved for the *.twiterhero.blogspot.com domain. The validator tool shows the domain is approved
The Card code though only works on one subdomain page - http://twiterhero.blogspot.com/p/trans1110-top-twitter-followers.html
Other links like http://twiterhero.blogspot.com and http://twiterhero.blogspot.com/p/luna1177-top-followers.html do not show the summary card.
Spent hours look for an answer. Hoping I can get some help or clue what to do. Thanks so much for reading.
