Fixed this by adding missing intent flags in AndroidManifest. Weirdly, it was working with some other Android 11 devices, such as Samsung and others

<queries>
  <intent>
    <action android:name="android.intent.action.SENDTO" />
    <data android:scheme="mailto" />
  </intent>
</queries>

well adding the flags does indeed fix the issue. I'm closing this one.

I think this exception is very poorly named. If it was something more like "Android Intent Missing From Manifest" or something like that then it's a better clue of where to start looking. The exception thrown here sounds like it doesn't work because the feature is not implemented in the library.
