Hello! There seems to be a problem with @font-face in Medicenter theme (maybe more ones…?) with content blocker on. (Firefox Focus App)
Is that because of google loads the font in the theme on some wierd way? I have sites that loads the @font-face directly in style.css, where it works fine.
These issues are usually related to the browser, as Firefox is not a native browser and they add their own “game changing features” to the mix, sometimes they can cause issues.
Are you seeing this issue in Safari, the native browser?
Cheers! 
Hello! Yes, it´s in Safari on iOS with Firefox Focus App enabled.
