Hello! I understand you're having trouble seeing sleep health statistics like heart rate, respiratory rate (RR), and oxygen stats on your VeryFit watch under the Sleep section. Let's get this sorted out.

To better assist, could you tell me:
- Which VeryFit watch model and app version you are using?
- Have you noticed if other health data (like steps or general heart rate) shows correctly on the watch or app?
- Have you tried syncing the watch and app recently or restarting the devices?

In the meantime, here are some common steps to try for this issue:

1. Check Permissions in the VeryFit App
Open the VeryFit app on your Windows device and ensure that all permissions related to health data — especially heart rate, respiratory rate, and oxygen saturation — are enabled. Sometimes, these need explicit permission to be displayed in the Sleep section.

2. Sync the Watch and App
Make sure your watch is properly connected and synced with the app. Try manually syncing by refreshing or opening the app while the watch is nearby.

3. Enable Sleep and Health Tracking on the Watch
On your watch, verify that sleep monitoring and vital sign tracking features (heart rate, SpO2) are enabled before you go to sleep. Some models require you to turn on specific monitoring modes.

4. Update Firmware and App Software
Check if there are updates available for your watch firmware and the VeryFit app. Updates often fix bugs or improve syncing.

5. Clear Cache or Reinstall the App
On your Windows device, try clearing the app’s cache or uninstall and reinstall the VeryFit app to clear any data issues.

If these steps don’t bring the sleep stats back, there could be a deeper syncing setting or data permission issue. Let me know what you've tried so far, and I can guide you further or check more specific settings.
