Folks there is an issue with Safari 13.0 on macOS Mojave 10.14.6 beta 3.
Safari does NOT show any google fonts either online or local. All other browsers do.
The funny thing is, that on Catalina beta2 Safari 13.0 does show the fonts.
This seems to be a bug in the OS not in Blocs.
I just wanted to let you know.
I was going to download that yesterday, then decided against it. I am curious why this would be blocking Google fonts specifically, especially if hosted locally on the server. I am running Mojave 10.14.5.
I installed Safari 13.0 on MacOS 10.14.5 and Safari shows all google fonts.
So the problem seems to be with the Beta3 of 10.14.6.
Why not self host the fonts instead? That should work.

On a broader note the number of people using Safari 12 on Mojave must be very small indeed now. It’s not that secure being on the internet with this combination and I imagine there are various compatibility issues.
There isn’t much I can add regarding WordPress if you are using a theme that is not created by Blocs.
