Selected fonts in Microapps don't always display in the final version of the Microapp.
- Content Microapps
Choosing a font in a Microapp in Studio does not display that font in the user-facing Microapp. This only appears to affect Microapps where the 'Font Size' is set to a font size with a percentage '%', and doesn't affect older Microapps (unless the font size is updated on them to one of the percentage font sizes).
For users this means that they will see a standard system font on the Microapp, rather than the font that was selected in Studio.
