AP's list of available fonts in the Text studio includes many noto font families. I haven't installed any noto fonts. Other iOS apps that use system fonts (for example Apple Pages) don't show these fonts. My app AnyFont doesn't show noto as an installed system font. In my Settings/General/Profiles I don't see any profiles for noto. Therefore it seems that somehow the noto fonts are coming with AP.
I'd like to be able to delete these noto fonts, because they clutter up my font list. Other people would like to be able to delete them too, see this thread:
