According to We’d love your feedback on our new app-only comment additions, a
previews API element was added to stories for creating specially formatted comments like
Asana for Gmail does. We have not seen any further progress on this. Has this been fully implemented or abandoned?
If this has been implemented, can someone direct how it is used through the API (POST-ing with a
previews data element doesn’t appear to work)?
If invite only, can someone direct who to contact because the link on the previous post does not get a response?
If abandoned, why?
