Twitter product card doesn't work like in example



In example:
But in real site with data from example( example: )
I just copied metadata from example

<meta name="twitter:card" content="product">
<meta name="twitter:site" content="@iHeartRadio">
<meta name="twitter:creator" content="@iHeartRadio">
<meta name="twitter:title" content="24/7 Beatles — Celebrating 50 years of Beatlemania">
<meta name="twitter:image" content="">
<meta name="twitter:label1" content="Genre">
<meta name="twitter:data1" content="Classic Rock">
<meta name="twitter:label2" content="Location">
<meta name="twitter:data2" content="National">

, but this is doesn’t work. What i’m doin wrong?


The the top of the documentation page it says:

This Card was be DEPRECATED on July 3, 2015 and has been mapped to the Summary Card.

Product cards will no longer be rendered.


Thank you. Sorry for my inattention.
