I don't know if it was solved but I made a small report on Twitter about a little problem I encountered.
(edit: tested, it hasn't been solved yet)
Contrast this with the normal behaviour where a link should become embedded as a media card on Twitter for the best sharing experience.
Thanks, should be working now. But please don't share links to the beta website. I'm not sure it will be available forever also after the final release.
Hahaha, alright. But if you move beta to production, and it's not working, it won't work in production either! :D
