expo-av bare Error: Missing audio recording permissions - react-native

Question

Was looking to use the recently available expo packages for detached or "bare" apps in react-native.
Running into the following error:
Error: Missing audio recording permissions.
however I have already called the expo-permissions library to ensure RecordAudio permissions are obtained.
See https://github.com/Glorifundel/bareaudio for full example project
App.js
import React, { Component } from 'react';
import { Platform, StyleSheet, Text, View, Button } from 'react-native';
import * as Permissions from 'expo-permissions';
import { Audio } from 'expo-av';
export default class App extends Component {
render() {
return (
<View style={{ flex: 1 }}>
<Text style={styles.welcome}>Welcome to React Native!</Text>
<Button title="Get Permission" onPress={this.onPressPermission} />
<Button title="Record" onPress={this.onPressRecord} />
</View>
);
}
onPressPermission = async () => {
const { status, expires, permissions } = await Permissions.askAsync(
Permissions.CAMERA_ROLL,
Permissions.AUDIO_RECORDING
);
alert(`permission: ${status}`);
};
onPressRecord = async () => {
const recording = new Audio.Recording();
try {
await recording.prepareToRecordAsync(
Audio.RECORDING_OPTIONS_PRESET_LOW_QUALITY
);
await recording.startAsync();
alert(`onPressRecord recording!`);
} catch (error) {
alert(`onPressRecord error: ${error}`);
}
};
}
Pressing the "Get Permission" button reports an alert "permissions: granted", following that up with pressing the "Record" button results in an alert "onPressRecord error: Error: Missing audio recording permissions."
Any insight is appreciated,
Environment details: I am running on windows 10, on an android emulator running android API 27 (8.1 Oreo). Did a fresh Node v10.15.3 install as well as a fresh react-native-cli expo-cli install and generated the project with expo init --template bare-minimum. followed up with yarn add expo-av and yarn add expo-permissions, followed the instructions found on the readme for the two packages.

async function startRecording() {
try {
console.log('Requesting permissions..');
await Audio.requestPermissionsAsync().then(() => {
console.log('Permission granted!');
})
.catch(error => {
console.log(error);
});
await Audio.setAudioModeAsync({
allowsRecordingIOS: true,
playsInSilentModeIOS: true,
});
console.log('Starting recording..');
const { recording } = await Audio.Recording.createAsync(
Audio.RECORDING_OPTIONS_PRESET_HIGH_QUALITY
);
setRecording(recording);
console.log('Recording started');
} catch (err) {
console.error('Failed to start recording', err);
}
}
