My favicon appears in browsers, appears when added to iOS home screens, appears when added Android home screens, but when I try to “Add to Favorites” in iOS, the icon does not appear. It won’t appear in the favorites screen either. I tried the just using customizer to add an icon file. I tried using the plugin Favicon by RealFaviconGenerator to add it, and while that gave me a lot more Favicon options for various devices, it did not fix the issue.
Here is what it looks like on iOS:
