Not all apps support custom fonts. If your font isn’t showing up in an app or program, try a different app to check if the font is installed and working properly.
To check if a font is installed, open Font settings. Select Start > Settings > Personalization > Fonts, and search for the font under Available fonts.
If your font is installed but still not appearing in an app, it may not meet current TrueType font standards. Choose an alternative font and try again.
