Custom font doesn't work on mobile

Site URL: http://www.definepilates.co.nz

Hey team - total novice here!!

Can anyone help me to understand why our custom font doesn't work on mobile - but it does on desktop? 

Our website is definepilates.co.nz 

Our code for the font is  below ( I think!). 

Thanks loads

Vicky

Hi, the fonts are showing up fine on my end (picture below), but your custom font css code has an error. You forgot to remove 'FONTURL' in the code which may be causing the issue. Here's the re-formatted code:

@font-face {
  font-family: 'commuterssans';
  src: url('https://static1.squarespace.com/static/620849d5fcf266763285fceb/t/621e669c21e49a69ca53177b/1646159516508/commuterssans-semibolditalic.otf') format('truetype');
}

@font-face {
  font-family: 'Branch';
  src: url('https://static1.squarespace.com/static/620849d5fcf266763285fceb/t/621e66b57f53f92a8feb36ad/1646159542315/Branch.ttf') format('truetype');
}

And just a tip! Commuters Sans is available in Squarespace via the Site Styles. You may remove the code for it and activate it on the website which actually improves site speed. Let me know how it goes 🙂
