Hi there! I understand you're seeing an error with the Pingo app that says it "cannot access statistics file." Let's work together to get this sorted.

To start, could you tell me if the app has permission to access files or storage on your iPhone? Also, has this issue just started recently, or has it been ongoing? Have you tried any steps like restarting the phone or reinstalling the app already?

Meanwhile, here are some straightforward steps to try:

1. Restart your iPhone: Sometimes a simple reboot can clear temporary glitches.

2. Check App Permissions:
- Go to Settings > Privacy & Security > Files and Folders or Local Network (depending on iOS version).
- Find Pingo and ensure it has access.

3. Update the Pingo App:
- Open the App Store, tap your profile icon, then scroll to check for updates and update Pingo if available.

4. Reinstall the App:
- Delete the Pingo app from your device.
- Restart your iPhone.
- Download and install Pingo again from the App Store.

5. Check Internet Connection: Since Pingo relies on network connection, make sure you have a stable Wi-Fi or cellular data connection.

If after these steps the problem persists, there might be something specific with the app’s data or cache permissions that can be addressed by the developers, or there could be an issue syncing data on their servers.

Would you please let me know how these steps go and if you notice any other error messages? That way I can guide you further!
