If the "Now Streaming" notification is no longer being added to your device's notification tray when you're listening, check to make sure your device hasn't been told to never show the app's notifications.
To do that, follow these steps:
- Go into your device's Settings area
- Select "Apps"
- Select "Scanner Radio"
- Select "Notifications"
- Make sure "Show notifications" is turned on (or, if you see "Block all" (or a similar sounding setting), make sure it's turned off).
- If you see "Now Streaming" listed, make sure it's enabled.
