Tried that, didn't work unfortunatly.
And even if it worked for Typekit, it doesn't explain why @font-face fonts are not working.
Hopefully the project will go live today, so I can share the URL.
Thanks, if/when you can share the URL that will be very helpful to us.
The site went live yesterday so here's the URL: http://www.blauwevnw.nl
With @font-face we use Modern Pictograms Pro2 and with Typekit we use Din.
Hopefully you can find the cause of the fonts not showing up in Edge Inspect.
