Fontello Font loading issue, preventing menu from being accessible on iOS

Hi there,

I have an issue with my site: https://www.empirelegal.com.au/

This is issue is specifically for iOS, and can only be replicated on an iPhone or by using an iOS simulator. The site works fine on Android and desktop emulating a mobile.

The burger menu when you click, will flash but does not open the flyout menu. When I’ve checked for errors, It does load, but only after 3 attempts, something to do with a 404 redirect using a fontello font. The first time it tries to get the woff file and fails. The second time it tries to get the ttf file and fails. The third time it tries to get the svg and fails. Then it loads.

Any suggestions as to how to rectify this issue would be greatly appreciated.
