Raleway font not bold on mobile

Hi! You helped me with this problem over here:
https://kriesi.at/support/topic/google-font-not-bold-on-mobile/

But now I’ve moved the site to the original domain, so the site is live and I see on Safari mobile that the font is not bold anymore. Don’t know exactly since when it’s not bold anymore, but do you have any ideas why it’s not bold on mobile safari browser. On desktop browser Safari and Chrome are both bold! So it’s only mobile!

See new link and login details in private content.

Maybe it’s since an update? But the raleway font is still added to import/export in Enfold theme settings!

Hope you can help! Janneke
