Social media embeds

Are you following this process ?

And when you say “It’s not working” – do you mean it throws an error, or do you mean your embed code simply does not display ?

It would help if you tried it on one of your posts, then published the post, then shared the URL here so we can take a look.

It was displaying an error message, but I used the first link you posted and it worked! Thank you so much
