Unable to make changes to source object in polar array

[Anonymous]

Hello. I am quite new to AutoCAD and I'm learning about polar arrays. I'm trying to edit the source object of a polar array but the commands and the array edit menu are quite different from AutoCAD for Windows (the interface that my course uses) and I can't figure out what I'm doing wrong. What should I be doing so that the change on the source object repeats on the rest of the array? 

Screen recording of my process below.

Hi Kelsey,

I am able to edit array source on my side with the way you show and changes applied to all objects in array (see attached screencast).

I don't see command line output at last stage on your screencast. Can you expand command window and look at it during your workflow with editing array source? What do you see?

Can you also share the drawing with array you are trying to edit? I want to look at it.
