Hi there! Sorry to hear your Yahoo Weather app is being unresponsive on your iPhone. Let’s get that sorted out together.

First, can you tell me a bit more? For example:
- Does the app freeze immediately on launch or become unresponsive after some use?
- Have you tried closing the app completely and reopening it?
- Is your iPhone’s iOS version fully up to date?
- Have you recently updated the Yahoo Weather app, or has this problem started suddenly?

Meanwhile, here’s a good step-by-step approach to try and fix the app not responding on your iPhone (iOS 26.2.1):

1. Force close the app:
- Swipe up from the bottom of your iPhone screen and pause in the middle to bring up the app switcher.
- Find Yahoo Weather and swipe its window up to close it completely.

2. Restart your iPhone:
- Press and hold the side button and either volume button until the power off slider appears.
- Slide to power off, then turn your iPhone back on after 30 seconds.

3. Check for app updates:
- Open the App Store, tap your profile icon, then scroll to see if an update for Yahoo Weather is available. Update if so.

4. Reinstall the app:
- Touch and hold the Yahoo Weather app icon until it jiggles.
- Tap the “-” or “Delete App,” then confirm.
- Go to the App Store and reinstall Yahoo Weather freshly.

5. Check System Updates:
- Go to Settings > General > Software Update and ensure your iPhone has the latest iOS version installed.

These steps refresh app memory and solve many unresponsiveness issues1 2.

If this doesn’t resolve things, I can guide you through more advanced troubleshooting or verify if there is any ongoing issue with Yahoo Weather servers.

Let me know if you’ve tried any of these or if you need help with a particular step!
