[Bug]: Push notifications not appear on specific android devices

[pawegio]

What happened?

I am not receiving push notifications on specific (not all) android devices. No issues on iOS. Problematic devices are:

• Samsung Galaxy A12
• Xiaomi Redmi Note 8

OneSignal Setup is following:

OneSignal.Default.Initialize(appId);

var result = await OneSignal.Default.PromptForPushNotificationsWithUserResponse();
// it returns expected NotificationPermission.Authorized result

if (result != NotificationPermission.Authorized)
    return;

OneSignal.Default.NotificationWillShow += _ => null;
OneSignal.Default.NotificationOpened += OnNotificationOpened;

Steps to reproduce?

1. Install and launch the app.
2. Background the app.
3. Trigger the notification from app server.
4. Push notification is not appearing.

What did you expect to happen?

Thanks for reporting

Could you provide another log with verbose logging by adding OneSignal.Default.LogLevel = LogLevel.Verbose; before OneSignal.Default.Initialize(appId);

Are the devices getting registered on the OneSignal dashboard? If they are, what are the Subscribed statuses of the devices?

Closing this old issue. It was caused by app id mismatch.
