Hi there! I understand your S-Miles Installer app on your Kindle (Android 11) has stopped showing usage data. Let’s figure this out together.

Could you tell me a bit more? For example:
- Are you still able to log in to the app successfully?
- Is the app failing to connect to your solar system’s DTU (data transfer unit)?
- Has anything changed recently, like your Wi-Fi network, device settings, or app updates?

This info will help me narrow down the cause.

Meanwhile, here’s a basic checklist we can start with:
1. Check Wi-Fi connection: Make sure your Kindle is connected to the same Wi-Fi network the DTU is using. Incorrect passwords or network changes can disrupt the communication.
2. Confirm DTU status: Is the DTU powered on and connected properly? Sometimes it needs a reset or power cycle.
3. Verify app login: Ensure you are logged into the S-Miles Installer app with a valid installer account. First-time users need to create an installer account before usage data can be shown.
4. VPN Check: If you use a VPN on the Kindle, try disabling it, as sometimes VPNs prevent the app from fetching usage data properly.
5. App update: Make sure your S-Miles Installer app is up to date via the app store on your device.

If these look good and the issue persists, we can try resetting the network config inside the app or verify if there’s a server-side outage that might be affecting data.

Let me know what you observe based on the above, and we can take the next steps from there! Are you currently logged into the app?
