Same happened to me- you just have to do it on the main page as well. For some reason that is separate from the others (at least on my template it was). The problem I came across was that changing the font of the title changed the copyright section at the bottom too. How did you unlink yours bc it doesn’t appear to be that way on your site?
I have yet to be able to change anything. It says pick element on a page, but as soon as I pick anything of course it just refreshes the page. I am talking about wanting to change Title texts and menu texts. I haven’t even been able to change simple text on a page.
