Hi! I understand your Yahoo Weather app keeps jumping or switching to Quincy as the location—let’s get this sorted out. Just to clarify: does it always switch to Quincy no matter what location you set? Also, are you using the app or accessing Yahoo Weather via a WebKit browser on your Windows 10 device?

Meanwhile, a common cause for this is the app defaulting to a saved or detected location, possibly Quincy, due to location permissions or saved locations list. Here’s a simple step-by-step guide to fix this:

1. Check Saved Locations in Yahoo Weather
- Open Yahoo Weather.
- Go to Settings or Locations (often an icon like a gear or a list).
- See if Quincy is in your saved locations. If yes, try removing it or setting your preferred location as default.

2. Enable or Adjust Location Permissions
- On Windows 10, open Settings → Privacy → Location.
- Make sure location services are turned on for your device.
- Scroll down and check that your browser (WebKit environment) has permission to access location.
- If you prefer to set the location manually, you can also disable location access to prevent auto-switching.

3. Clear Browser Cache and Cookies
This removes any stored information that might cause location to revert.
- In your WebKit browser, clear browsing data (cache and cookies).
- Restart the browser and reopen Yahoo Weather.

4. Manually Add Your Preferred Location in Yahoo Weather
- Tap on “Edit Locations” or the equivalent.
- Use the “Add” icon and enter your city or ZIP code.
- Set this location as default or remove other unwanted locations.

5. Check for any Account Settings
- If you are signed in, sometimes Yahoo account settings can override local settings. Log out and see if it still switches. If not, review your Yahoo account location preferences.

If you try these and still experience the issue, let me know which steps you have done already, and we can go deeper. Does that sound good? I’m here to guide you through it!
