For the mileage calculator to work, it needs access to your location. To enable location services, go into your device’s settings. The process to do this can vary depending on whether you're using a laptop or a phone. Once you've enabled location services, you should see a map in the app.

If you're unsure how to enable location settings on your specific device, a quick internet search with your device model and 'enable location settings' should provide step-by-step instructions.

After turning on location services, close and then reopen the app or refresh the webpage, allowing the changes to take effect.
