As of few hours ago, we started noticing that CARD_URI response attribute is populated with a value with following format: card://xxx (when creating website cards). What’s with the new format ? and why is it so different with “preview_url” format (i.e., https://cards…") ?
The migration guide (Ads API Version 2) mentioned that not all cards supports this “card_uri” attribute. May I know what are those cards ?
