Although I have uploaded my adobe fonts kit and assigned my fonts properly through theme’s settings, there are still some areas on the website where I see another font, named system font, Segoe. How can I disable that? I want all areas to have my adobe fonts.
Yep, try to set the font via Advanced Typography in Theme Settings -> Typography -> Advanced and create a rule with the “Custom selector”: https://prnt.sc/iK5sA7bA-1hm
Then put the selector in which the font is not changed.
