This question was asked several times in this forum but the answer was always to use the code to add font to the list. In my case, I need to have ALL Google fonts loaded so that I can select them in the Customizer in order to see the results. As I still don’t know which font will I use, I want to be able to cycle through all the available ones.
I cleared all caches. I even tried to use “return 900;” instead of “return ‘all’;” but still no luck.
