Font "Shantell Sans" not being downloaded

Question

I am trying to use this font from Google Fonts for my Android app. I want it as a downloadable font.

So, I have on res/fonts folder this xml:

<?xml version="1.0" encoding="utf-8"?>
<font-family xmlns:app="http://schemas.android.com/apk/res-auto"
        app:fontProviderAuthority="com.google.android.gms.fonts"
        app:fontProviderPackage="com.google.android.gms"
        app:fontProviderQuery="Shantell Sans"
        app:fontProviderCerts="@array/com_google_android_gms_fonts_certs">
</font-family>

But when I run my app, it loads the default font instead of Shantell Sans.

If I try other fonts like "Hi Melody" or "Patrick Hand" in fontProviderQuery, the font is loaded correctly.

app:fontProviderQuery="Hi Melody"

app:fontProviderQuery="Patrick Hand"

According to the official documentation all fonts from Google Fonts can be used.

Which fonts can I use?

The entire Google Fonts Open Source collection! Visit https://fonts.google.com to browse.

So, why is "Shantell Sans" not loading?
