SplitView Resizing Issues in OS 10.14 Mojave

in Genius Bar
Wondering if anyone else is having issues resizing Split View windows in OS Mojave.  I'm specifically having issues on a secondary monitor, where I can put two apps in the full-screen "Split View", but then can't adjust the width of the apps (meaning the vertical black separator doesn't slide left/right.. the cursor changes to the 'left/right' arrow, but nothing happens). 

I'm on a 2017 13" MacBook Pro, and am using an LG Ultrawide monitor via HDMI.  While on High Sierra I was able to adjust application widths in Split View via this same hardware setup, but since the formal Mojave release it hasn't worked.

I've tried the basics: reset, hard-reset, unplug/plug monitor, etc.  Any advice or feedback would be really helpful!!

    Yes I have exactly the same issue with my 2017 macbook pro running Mojave (2nd monitor is a 27" Acer Predator). It used to work fine before I upgraded as well...
