Soundcloud player iframes not working after update

After this morning’s update, soundcloud iframes on my amp page have had some problems.

Soundcloud <amp-iframe> is being rendered with no width. ie set as width=””. This results in a big empty space on the page wince the height is still set.

Even after adjusting the css, the player still won’t function. I just see the placeholder.
