Hi there! I understand you're having trouble with the SmartHealth app not saving your height or weight even after trying various troubleshooting steps. I’d like to help get this sorted out for you.

To start, could you please tell me:
- Are you manually entering height and weight or trying to sync from a smart scale or device?
- If syncing, do you have the device successfully connected to the app?
- Have you checked if the app has all the necessary permissions enabled, like location or storage access?
- Is your app fully up to date from the Play Store?

Meanwhile, here’s a step-by-step approach to resolve the issue if you haven’t tried these specifically yet:

1. Verify permissions:
On your Android 10 device, go to Settings > Apps > SmartHealth app > Permissions. Ensure Location, Storage, and any other relevant permissions are enabled. Sometimes apps can’t save data without required permissions.

2. Clear app cache:
Go to Settings > Apps > SmartHealth > Storage > Clear Cache. This won’t delete your data but can clear temporary issues preventing saving.

3. Manual entry method:
If syncing doesn’t work, try manually entering height and weight again but this time:
- Enter the values, then wait a few seconds before tapping “Save” or “Confirm.”
- Avoid navigating away too quickly after input, to ensure data saves properly.

4. Reboot the device:
Restart your phone to refresh background services and app connections.

5. Check for app updates:
If not up to date, an old version may have bugs that prevent saving data.

6. Reinstall the app:
If the problem persists, uninstall and reinstall SmartHealth. This can fix corrupted app files.

If syncing a device like a scale is involved, also ensure:
- Bluetooth is enabled and paired correctly.
- Location sharing is enabled while pairing (some Android apps require this).
- The scale and app firmware are up to date.

If you’ve already tried these and the problem continues, let me know which ones so we can dig deeper or possibly check for account or server-side issues.

Are you able to try these steps for me? Let me know how it goes!
