Hi there! Thanks for reaching out about the mileage issue in your MyNISSAN app. From what you've said, it sounds like both the "mileage to empty" and your past month's mileage are showing the same values and not updating correctly. Just to get a better picture, could you tell me:

- When did you first notice this mileage data stop updating?
- Have you recently reset or updated anything on your vehicle or the app?
- Are you seeing any other issues with the app, like connectivity problems or trouble with other vehicle data?

This info will help me guide you better. Meanwhile, I'll share some general steps that often help resolve this kind of problem:

1. Check Vehicle Data Sharing Settings: Sometimes the app stops updating because the vehicle isn’t sharing the necessary data. In your car’s infotainment system, navigate to Info > Nissan Connect Services > Vehicle Data and ensure that data sharing is enabled.

2. Refresh Connection: On your Windows device, try signing out from the MyNISSAN app and then signing back in. Also, make sure the app is updated to the latest version.

3. Restart Your Vehicle and Mobile Device: A simple restart of both can often reset connections and resolve syncing issues.

4. Internet Connection: Since the app relies on good network connectivity to sync mileage, double-check your device’s internet connection is stable.

5. Check for App or Vehicle Updates: Sometimes mileage syncing issues are related to outdated software. Verify if there are updates for your vehicle’s firmware (via your dealer or Nissan’s support) and the MyNISSAN app itself.

If these steps don’t resolve the issue, the problem might be deeper—like the app’s connection to your vehicle’s telematics system, or a need to resync the vehicle data through your dealer.

Would you like me to walk you through checking the vehicle data sharing setting on your car's display, or help with app sign-out and reinstall on your Windows device?

Also, feel free to share more details based on my questions!

Are you satisfied with this initial guidance?
