If your project's Target Android version is set to Android 11 (R API 30) or higher, you must update your Android Manifest with queries that use Android's  package visibility requirements.

In the Platforms/Android/AndroidManifest.xml file, add the following queries/intent nodes in the manifest node:

<queries>

  <intent>

    <action android:name="android.intent.action.SENDTO" />

    <data android:scheme="mailto" />

  </intent>

</queries>
