How to change SUBTITLE textAppearance in NavigationView? For NavigationView material component. Here is the documentation: https://material.io/components/navigation-drawer/android#anatomy I think there is no way to change it, but let's give it a try.
I was following theming from here: https://material.io/components/navigation-drawer/android#anatomy
Only overriding style changed the subtitle text appearance:
<style name="TextAppearance.AppCompat.Body2">
<item name="fontFamily">@font/montserrat_light</item>
<item name="android:fontFamily">@font/montserrat_light</item>
<item name="android:textColor">@color/colorRed</item>
</style>
