Hello! I see you're having trouble with your Eros Scale app not registering weight and no syncing happening. Let's figure this out together.

First, to better assist you, could you tell me:
- Are you able to turn on the scale and see your weight on the scale’s display itself?
- Is Bluetooth enabled on your phone?
- Does the Eros Scale app open normally, and does it give any error messages when you try to sync?
- Have you tried restarting your phone and the app already?

These details will help me pinpoint the issue. Meanwhile, here’s a basic step-by-step approach that usually helps resolve syncing and registration problems on Android devices with Eros Scale:

1. Check Bluetooth connection: On your Android 10 device, confirm Bluetooth is turned on in Settings. Also, make sure the scale is in pairing mode (often it does this automatically when you step on it).
2. App permissions: Go to Android Settings > Apps > EROS Scale app > Permissions. Ensure it has permission to access Bluetooth, location (sometimes necessary for Bluetooth scans), and storage.
3. Restart devices: Power off your scale (remove batteries for 10 seconds if possible) and restart your phone. Then, open the app first before stepping on the scale.
4. Stay close by: Keep your phone within a few feet of the scale during measurement and syncing.
5. Update the app: Check the Google Play Store for any updates to the EROS Scale app and install them.
6. Reinstall the app: If none of the above help, uninstall and reinstall the app to clear any possible glitches.

If you follow these steps and still see no weight registration or sync, there might be a need to check for firmware updates on the scale or deeper troubleshooting, such as clearing the Bluetooth cache on your phone or checking for interference from other devices.

Please let me know what you’ve tried so far and what you observe when using the scale and app. We’ll get this sorted soon!
