Presenting Keynote - Couldn't Get Out of Presenter / Split-Screen Mode

I have used Zoom for most of my 184 Keynote shows. Tonight, I was not able to show my file as a single-screen/slide. It showed the group the Presenter Screen - with the Next Slide showing. Something changed - not as intuitive as before.

Also - Share Computer Audio. I find it. I click on it. I chose Mono. But my audience never heard the audio clips. THAT really is annoying. I see no difference in my local screen between NOT sharing audio and sharing audio.

Zoom for Mac. Upgraded this afternoon to the latest version.
