Hi there! I understand that Map My Walk stops working when you enter a building. That can be a common issue due to GPS signal limitations indoors. Can you let me know if you're experiencing this consistently in all buildings or just specific locations? Also, does the app provide an error message or just stop tracking entirely when this happens?

In the meantime, here are a few steps you can try that may help:

1. Check GPS Settings: Make sure that your GPS is enabled on your Android device. You can usually find this by going to Settings > Location and ensuring that it's turned on.

2. Offline Mode: Sometimes switching to offline tracking mode can help when indoors. Check if your app has this feature and enable it before you enter the building.

3. Network Connection: If you're relying on a mobile data connection for GPS, it can get interrupted inside. Ensure that you have a stable Wi-Fi or mobile data connection, if available.

4. App Permissions: Double-check the app permissions to ensure that Map My Walk has access to location services. You can do this in Settings > Apps > Map My Walk > Permissions.

5. Restart the App: If the app has stopped tracking, try closing and reopening it to see if it starts working again.

If these steps don’t resolve the issue, let me know, and I can assist you further. It may be helpful to look into more advanced troubleshooting. Are you satisfied with the solution I provided?
