Hi there! I understand you're having trouble adding new locations to your saved locations in the WeatherBug app on your iPhone. Let's get this sorted out together.

To begin, can you tell me a bit about what happens exactly when you try to add a new location? For example, are you seeing an error message, or does the app just not respond?

In the meantime, here are some straightforward steps to try:

1. Adding a Location Step-by-Step
- Open the WeatherBug app.
- Look for the "+" symbol at the top right of the screen and tap it.
- Type in the name of the location you want to add.
- Tap "Save" in the top right corner.

2. Check for Duplicate Locations
- Sometimes, if you already have that location saved, the app won't let you add it again. So double-check your saved locations to avoid duplicates.

3. Verify Location Permissions on iOS
- Go to your iPhone's Settings > Privacy & Security > Location Services.
- Ensure Location Services are ON.
- Scroll to WeatherBug and make sure it's allowed to access your location either "While Using the App" or "Always."

4. Update the WeatherBug App
- Open the App Store and check if there are any updates available for WeatherBug. Running the latest version helps avoid bugs.

5. Restart Your iPhone
- Sometimes a simple restart can refresh the app and system resources.

After you've tried these, let me know if the problem persists or if anything behaves differently. We can then dig a bit more deeply into settings or account factors.

Are you able to try these steps and tell me how it goes?
