There is no pop up notification

Dear Admin,

I'm using a iPhone 6 Plus with iOS 8.1.1.

Although I activated the notification when AQHI reach Very High and Serious levels for both Roadside and General Air Monitoring Stations, there is no pop up notification from the App.

I would be most grateful if you could follow up the issue as the pop up notification is very important to me.

Best Regards,
Edwin YU
