Hello Friends,
I too encounter the same problem, but afterword realize that I was making a small mistake.
Go to Settings/Google Fonts
-Click “Create a New Font Control”
-Name it “Home Headline”
-Click “Save Font Control”
-Under Add CSS Selector type “.home-headline”
Here I was missing preceded dot(“.”) which was creating problem for me.
.home-headline
it is right way.
thanks a lot.
