I was recently approved for large summary cards, and following the advice in the validation email, I chose to apply for validation for summary cards, which also was approved. However, since my blog is hosted on wordpress.com, I don’t have the ability to add metadata to pages. Am I able to affirmatively choose which card I want to use for each tweet I post or will one of these cards simply become the default? My website is visualventuring.com. Thanks in advance for any guidance.
