And now when calling to initialise this it's failing, but the callback returns null so I dug through to see where it was failing.

EmojiCompat.init(
    FontRequestEmojiCompatConfig(
        this,
        FontRequest(
            "com.google.android.gms.fonts",
            "com.google.android.gms",
            "name=Montserrat",
            R.array.com_google_android_gms_fonts_certs
        )
    ).setReplaceAll(true)
)

The error that it's throwing internally is;

android.content.pm.PackageManager$NameNotFoundException: No package found for authority: com.google.android.gms.fonts

I can't find anything to do with this issue anywhere.
