Camera Zooming on Zoom

Since the latest "upgrade" my camera now has lost its "zoom" (Ironic, right?) and "zooms out" to a wider angle - meaning a previously hidden parts of my office are now on screen.  

I have discovered that I can replace my live image - turn video off and my portrait picture appears and then when I resume video, the camera is again in the original "zoomed in" mode.  But the second I talk, it zooms back out. And then stays in wider angle mode. 

C'mon guys - one of the reasons I love Zoom is that it, uh, "zooms in"- and makes my image larger. And hides my floor piled high with file folders.

Oddly, other meeting participants seem unchanged in the field of view.
