I used to be able to pin to profile a working twitter player card and be able to on refresh of the page have the video playing on my profile page, but for some reason it no longer auto expands, has this feature been deprecated?
This is taken directly from https://dev.twitter.com/cards/types/player.
“When viewing a tweet with a Player Card on a desktop, the URL you specify via twitter:player will be rendered in an iframe in the timeline upon expand of the Tweet. (It will be shown automatically when the Tweet is pinned open on a user’s profile, or viewed on a Tweet permalink page.)”
