Also, did this problem surface using the exact demo we previously shared?

Re: Properly usage of getSVG() method

Hi,

Do you use the export server for this?

You need to insert the CSS of FontAwesome in order to use it.
You can test it here https://export.highcharts.com/ and place the JS and CSS into the corresponding fields to see that it works.
