Has the Audio transcript button disappeared?

Hi all,

I've been developing a course in Rise 360. As part of the lesson I have audio and I need to include the transcripts, which I'm doing manually (enabling the "Transcribe audio file" option). 

When previewing or after publishing to review, I can't see the "See transcript" button in the audio player. A couple of days ago it was there, and upon clicking it, the transcript would appear in a panel to the right side of the browser window, but now that button has disappeared from the player.

Was it removed on purpose or is this a bug after the most recent update (which I know modified some functionality in the audio blocks)?

Thanks for your insights! 

Julio
