Other Font-Awesome Icons Don't Render

[neilskilling-overskilling]

I am using the Hugo Universal theme and wanted to change some of the Font Awesome icons used in the features section.

If I try and use any other Font Awesome icon other than one that has previously been used in the site it doesn't appear. I am restricting my usage to the free icons.

For example if I change the content data/features/consulting.yaml line from:
icon: "fas fa-lightbulb"
to:
icon: "fas fa-dollar-sign"

then I just get a blank where the icon should be. Any suggestions?

Hmmm this seemed to work fine for me

icon: "fas fa-dollar-sign"
