I’m not at a desktop to check but this usually happens when you have two different FA versions loaded on your site.

I found both of these in my site script header, not on the arrowchat header
FA 6.5.0
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/ ... ll.min.css">

FA 4.7.0
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/ ... me.min.css">

I tried to remove them one at a time to see if it made a difference, it did not, the only time I see the missing icons is when I'm on my PC, not when using my phone, or using the code embedded on a page, just when using the chat popup., I clear my cache but made no difference.
