How do I activate Zoom on Pocket 2 when using the extension rod? (No attached smartphone)

I can select zoom on the screen menu, but it has no effect on the 4-way controller on the extension rod.

There also seem to be two ways to flip the camera 180 degrees.

Regards

Not using the extension rod, but I find that the 3-presses on the button does not flip the camera to face me. I have to go into the menu and flip it that way.  The manual is far from easy to comprehend.
