Hello
I’m just testing the plugin with a child site on a multisite network, and am seeing an issue with all icons on the page builder (the parent site is fine):

Not sure if this is any help, but here’s the inspect element output from the <i> element:

There is another plugin that has enqueued fontawesome, but this is identical on the parent site which is displaying icons fine.
The rest of the page builder is working perfectly on the child site, as far as I can see.
Thanks!
