I was glad to see the new SSL behaviour in 3.0.2 introduced, but I still don't get to see embeds displayed when browsing securely. From a look at the source, I can see the iframe is using a secure link, but the player does not display. Everything works as desired when browsing non-securely, even though the iframe code is the same.
When I take a look at the page source, the iframe is loaded using https
<iframe width="100%" height="166" scrolling="no" frameborder="no" src="https://w.soundcloud.com/player?url=https%3A%2F%2Fapi.soundcloud.com%2Ftracks%2F121955716&auto_play=false&show_comments=false&color=362f2d&visual=true&show_artwork=false">
However, Chrome inspector will still report this error:
[blocked] The page was loaded over HTTPS, but ran insecure content from 'http://w.soundcloud.com/player/?url=https%3A%2F%2Fapi.soundcloud.com%2Ftrac…play=false&show_comments=false&color=362f2d&visual=true&show_artwork=false': this content should also be loaded over HTTPS.
