Hi @tuanphan, I was wondering if you could confirm if Custom CSS allows to use Font Awesome 5 on a Personal plan.
@import url('https://use.fontawesome.com/releases/v5.13.0/css/all.css');
Icons appear when the Custom CSS page is opened (so when I'm loggedin to Squarespace) but icons do not appear when viewing the site.
The same occurs when trying your code for Font Awesome 4.
What do you think?
