I have implemented twitter cards for my site in accordance with my understanding of the documentation. When I validate either http://test-my.socialtoaster.com/TfvC or the associated t.co link http://t.co/AvG5fMfRFl I see the card exactly as I would expect it to be. However, when I posted this link in a tweet https://twitter.com/myvcomp/status/393370582110068737 the card does not display as it does in the validator. specifically these tags:
<meta name="twitter:site" content="@standingwoo"> <meta name="twitter:creator" content="@standingwoo">
are not being processed as expected. Instead socialtoaster.com is displayed as the author either because it was posted through the socialtoaster.com app or because the end domain is socialtoaster.com. Either way, this is not correct, according to the documentation and validator tool.
In addition for the last few days most links I shared did not receive cards for several hours if at all and some cards that showed up disappeared for a time only to come back later, despite the content not changing and the validator returning correct information.
