How to change the sub-menu indicator?


In the customizer > header > Nav Style I have the sub-menu indicator enabled. However, it seems to be locked onto a Font awesome Pro icon. Thus, unless I have FA 5 Pro enabled in BB settings it won’t display.

But enabling FA 5 Pro causes a remote load of the FA 5 css of 32k taking somewhere up to 2.8 seconds to load.

How can I change the sub-menu indicator to a different icon (maybe one of the dash icons) and get rid of the FA pro loading because I don’t use it anywhere.

Are there any other areas that BB uses FA Pro?
