We’ve implemented Twitter Summary Cards on our site, and are seeing the cards display. Problem being, they’re only appearing on SOME of the tweets that go out.
Check out this particular link:
The tweets from @lloyddobbler and @whosentit use the same shortened URL as the tweets from @FullContactAPI & @FullContactApp - the former don’t contain the card, but the latter do.
The tweets from @mattdelliott, @Ben_Deda, @BradMcCarty, and @Xorlev all run through the ift.tt URL shortener. 3 of them show the summary card, but one does not.
Any ideas why this would be happening?
