Hi, here is a recent example of embed code, not working:
<blockquote class=\"twitter-tweet\" data-lang=\"fi\"><p lang=\"en\" dir=\"ltr\">Were proud to be the only Western Conference team to finish without a losing record at Joe Louis Arena. <a href=\"https://twitter.com/hashtag/Farewell2TheJoe?src=hash\">#Farewell2TheJoe</a></p>— Vegas Golden Knights (@GoldenKnights) <a href=\"https://twitter.com/GoldenKnights/status/851181761023193088\">9. huhtikuuta 2017</a></blockquote><script async src=\"//platform.twitter.com/widgets.js\" charset=\"utf-8\"></script>
Ignore the forward slashes, this is from source data that comes via JSON string property, hence the escaping of quotes.
