Hi Julia
Thanks for reaching out
Could you please attach a screenshot of the issue? so we can get an idea of the issue exactly.
and this issue is not related to the free version.
Actually, there are two ways to change it. One from the Customizer ( Appearance ->Customize -> Typography Settings)
This customizer setting is for the blog pages, menu, page headings, footer, sidebar, etc)
Another one is from the Elementor page builder itself in which you can change the typography of each page section built with Elementor.
You can also email us at support@spiraclethemes.com if you face any issues uploading the screenshot.
Best Regards
