Hey @veha,

Can you share the relevant code to the issue? It would really help us debug what could be happening here.

Cheers,

Hi @adamjnav I using redux-saga

export function* createNotificationsAndroidChannels() {
  if (Platform.OS === 'android') {
    yield call(Notifications.createChannelAndroidAsync, 'main', {
      name: 'Main',
      priority: 'max',
      sound: 'default',
      vibrate: [0, 250, 250, 250]
    });
  }
}

In documentation sound (boolean) but I put text, can there be a reason in? But not all devices throw error…

hey @veha, were all the devices you ran on with Android Oreo or later? Notification channels are not supported pre-Oreo https://docs.expo.io/versions/latest/guides/notification-channels

Hi @quinlanj, I took this from docs:

On devices with Android 7 and below, which don’t support notification channels, Expo will remember the relevant settings you created the channel with (in this case, sound: true) and apply them directly to the individual notification before presenting it to the user.
