Why do custom fonts revert to default on mobile after publishing?

Hi! I added custom fonts to my theme, Streamline.

When editing my site, my fonts on the preview site look perfectly fine after I make changes.

However, once I publish my changes, the fonts revert back to default text in mobile view but my custom font stays in desktop view.

Preview site example - Mobile:

Live site after publishing - Mobile:

Any idea how to fix this?

Hello @joshw7 ,

  1. Check under media query is there font defined for mobile.

  2. Try to use !important with font-family you declared.

Thanks
