Hi there! I understand you're facing a connectivity message with the Mileage Tracker, but it seems like everything is functioning fine on your end. Let's dig a little deeper to see if we can resolve this.

1. Check Location Settings: Since Mileage Tracker relies on GPS data, please ensure that your device's location services are enabled for Mileage Tracker. You can do that by going to Settings > Location and checking if the app has the necessary permissions.

2. Reconnect to Internet: Sometimes, just toggling airplane mode on and off can refresh the connection. Give that a try to see if the app recognizes a better connection afterward.

3. App Update: Make sure you have the latest version of Mileage Tracker installed. You can check this by going to the Google Play Store, searching for Mileage Tracker, and looking for an update option.

4. Reboot the Device: Restarting your Android device can sometimes help clear up temporary glitches that lead to such messages.

5. Reconnect to WiFi or Mobile Data: If you're using a hotspot or WiFi network, try disconnecting and reconnecting to see if that helps. It can sometimes reset the connection effectively.

If you could try these steps and let me know if the issue persists, that would be great! Are there any specific experiences with the app that you've noticed which might give us more clues?
