Hi there! I see you're getting a big red cross in the Hume Health app when trying to start a measurement. I’d like to help you get this sorted. Just to clarify, when this happens, have you noticed any error codes or messages besides the red cross? Also, are you using a Hume Health smart scale, like the Body Pod, to take your measurements?

Meanwhile, a common cause of this problem is a connection or data transfer failure between the scale and the app. This often happens due to Bluetooth issues or interference.

Here’s a step-by-step approach to try and fix this on your Android 10 WebKit device:

1. Check Bluetooth Connection:
- Open your phone’s Bluetooth settings.
- Turn Bluetooth off, wait about 10 seconds, and then turn it back on.
- Make sure your Hume Health scale is powered on and near your phone.

2. Re-pair the Scale:
- Forget the scale device from your Bluetooth paired devices list.
- Restart your phone.
- Open the Hume Health app and follow the pairing instructions to connect the scale again afresh.

3. Close Other Apps:
- Sometimes other Bluetooth or health apps running in the background can interfere.
- Close any other apps that might be using Bluetooth or health data before measuring.

4. Check for App Updates:
- Visit the Google Play Store.
- Ensure the Hume Health app is updated to the latest version.

5. Restart the Scale:
- If your scale has a power button, turn it off and back on.
- If it uses batteries, consider replacing them if they are old.

If after these steps the red cross keeps appearing, the issue may be a data transfer error, sometimes marked as “error 10” in the app, indicating the scale and app are not communicating properly.

If you want, I can guide you through checking error logs or we can escalate this to technical support with Hume Health directly.

Does this align with what you’re experiencing? Have you already tried any of these? Let me know and we’ll go from there.
