What can I do if the application shuts down unexpectedly?

In exceptional cases, the application might shut down unexpectedly. Your device will display a system message to inform you (see below). After confirming the system message, you will be redirected back to the application or the device's home screen. Do not worry, your notifications are safe. Nevertheless, you should check whether or not the notification service is still running. If needed, start the service again and continue with your notifications as usual.
