Open product in the CPB App -> Settings -> Font Manager.
All the Google font family fonts are pre-uploaded in the App. On the right side of the Manager page, you can see all the fonts that are currently available for your customers. You can remove fonts from the list by placing them on the left side of the Manager. To do so – use arrow controls in the Middle. Double arrows move all fonts to one of the sides.
Adding custom fonts
To add a custom font you require a .ttf file of this font. Open the CPB app -> Global settings -> Drop the .ttf file of the font in the upload area. Once the font is uploaded in the Global settings you can manage them in the product. Custom fonts will appear at the top of the list.
