Twitter Card Type Changing Intermittently


#1

Our original Twitter Card was a Photo type; however, we changed to the new Large Summary card last week, and it works fine. However, some content still displays as Photo Card when posted on Twitter, while others (most) display as the correct one, Large Summary.

In both cases, the page source shows the correct card type in the meta tag, ie so any idea why it would still be displaying as Photo Card?
