This is what I am seeing on my phone on Chrome with the browser cached.
The 'Welcome to' text is in a sans-serif font. It should be in the serif Perpetua font which comes through fine on Safari and Chrome on my laptop..

Very confusing!

This is what i see on iPhone 7 on all browsers:

Well, I'm thoroughly confused haha. I've tested it on Firefox and Chrome on my Android phone and the font doesn't work properly on either browser. But it seems to be working absolutely fine on iPhones. I'm clueless.

Ill ask one of the team to check on their android phones.

Thank you David!

Spontaneously working now!

Awesome :) Glad to heat that
