Hi! Thanks for reaching out about your Metabolic Momentum not updating from your Hume Band. Since your daily metrics are syncing fine, it sounds like the Bluetooth connection is working well, which is great. To get a clearer picture and help you best, could you please tell me:

1. How long has this issue been occurring?
2. Have you recently updated the Hume Health app or your band’s firmware?
3. When you sync, does the app show any error messages or simply not update the Metabolic Momentum metric?
4. Are you syncing the band manually or is it set to auto-sync?

Meanwhile, here are some initial steps that often help with this specific issue:

1. Check app permissions and background refresh:
- On your Mac, ensure the Hume Health app is allowed to refresh in the background. This helps it keep all your metrics updated automatically. Since you’re using macOS 10.15.7, go to System Preferences > Battery (or Energy Saver) and make sure there are no restrictions on the app.

2. Verify data syncing with Apple Health:
- Open the Apple Health app on your device.
- Confirm that the Hume Band data, especially metabolic or activity info, is being synced there properly.
- If this connection is interrupted, parts of your data like Metabolic Momentum might not flow through.

3. Force a manual sync in the Hume Health app:
- Open the Hume Health app.
- Navigate to the “Me” tab (bottom right).
- Find a refresh or sync option and trigger it manually.
Sometimes manual syncing pushes through updates that auto-sync misses.

4. Restart devices:
- Restart your Mac.
- Turn your band off and on again.
This can resolve small connectivity hitches.

5. Update app and band firmware:
- Check in the Hume Health app for any updates available and install them.
- Likewise, check if your band has a firmware update pending.

If after trying these steps the Metabolic Momentum still won’t update, let me know, and we can explore more advanced fixes like resetting app cache or re-pairing the band.

How does that sound? If you'd like, I can guide you step-by-step through any of these.
