Font Awesome icons not displaying after upgrade to Joomla 4

Hi,

I have upgraded my client's website to Joomla 4 and notice that the Font Awesome icons (a Facebook icon in the socialrow and an up arrow in copyrightrow) are not showing.

The live site containing a Joomla 3 installation is at  holytrinityhampton.org.au/ . The Facebook and up arrow icons display properly, at or near the bottom of the website.
The staging site contains a Joomla 4 installation and is at  holytrinityhampton.org.au/j4/ . The icons do not display.

Are you able to throw some light on why the icons are not displaying in the Joomla 4 version, and what I can do to fix this?

Many thanks,
Julia.
