Hi there! It sounds like you're having trouble adding locations in the AccuWeather app. I'm here to help you sort this out!

To start, could you please tell me if you're receiving any specific error message when you try to add a location? Also, have you made sure that the app has the necessary location permissions enabled on your iPhone?

Let me guide you through the standard steps to add a location:

1. Open the AccuWeather app on your iPhone.
2. Tap on the "sandwich" menu (the three horizontal lines) located at the top left corner of the screen.
3. Select the "Location Search" field.
4. Type in the name of the location or its ZIP code you wish to add.
5. Once it appears in the search results, tap on it to add.

If those steps don’t work, please check your location settings. Make sure that location services are enabled for AccuWeather:

1. Go to your iPhone’s Settings.
2. Scroll down and tap on Privacy & Security.
3. Tap on Location Services.
4. Ensure that Location Services is turned on and that AccuWeather is set to “While Using the App” or “Always”.

Let me know if this helps or if you're still facing issues! Is there anything specific that seems to be problematic?
