Help with font loading on mobile in merch pages

Site URL: https://www.trickofthelight.co.nz/merch

Hi team,

Got another quirky issue with these two pages on mobile:

•  https://www.trickofthelight.co.nz/merch
• https://www.trickofthelight.co.nz/merch/p/troll-soundtrack

We need to use macrons for that special 'O' in Troll which means I had to load the full font from Adobe using their embed code as Squarespace only loads an un-extended version of any font. 

It works perfectly but for some reason it is not loading in the Shop or Merch sections on mobile. It loads on desktop fine.

I would love any suggestions as it is super weird  and the client would love to have it fixed.

Thanks in advance,

Brent
