Why can't Apple 6 bring its own weather refresh?

In this case, considering that your mobile phone has not been refreshed, first check whether the connection to the network is successful and whether the mobile data is turned on.

To display the weather in the notification, you need to set the following settings: Click Edit in the notification center, enter Settings-Privacy, and open the weather in this location.

Switch network data, choose to connect to WiFi, and see if it is solved.

Considering your usage, you can also download other weather software in the Apple Store to use the weather function.

You can also try to restart or shut down, and reopen the weather software to see if it is getting better.

Restoring mobile phone factory settings or restoring network settings is also a good solution.

If the above can't be solved, I suggest you go to Apple's after-sales service outlets for testing.
