Font Awesome not showing on my mobile

Hi, I am building a app based on a existing Bootstrap template. I use [fa][/fa] to show icons on my menu sidebar. When I test the app everything is fine on my laptop. But when I test it on my Android mobile phone in Chrome the icon doesn’t show. I also tested this in another browser on my mobile. What can I do about this?

The only thing I can think of is the Font Awesome library isn’t being loaded. Try making sure you have an icon element visible on the page when testing on your mobile.

This will ensure the library is getting loaded.
