Typography only displaying system fonts (Arial & Segoe) on front end

Hi,

I've set all the typography in the customizer to be 'Inter' Google font. When I'm editing a post it displays as Inter font but when I take a look at the front end, it only displays Arial or Segoe. I've gone over the typography settings in the customizer and double checked everything is set to Inter. Am I missing a setting somewhere that I need to change!?

Thanks
