Hi there! I’m Charlotte. I see you’re having trouble because your Hume Health app stopped working. Could you tell me a bit more about what you’re experiencing? For instance, is the app not opening at all, freezing, or not syncing data like it used to?

In the meantime, I can suggest some initial steps to try:

1. Restart your phone to refresh its system.
2. Make sure your phone’s Bluetooth is turned ON since the app often relies on it for data syncing.
3. Verify the app’s permissions:
Go to your phone’s Settings > Apps > Hume > Permissions and confirm that Bluetooth access is enabled.
4. If the app is unresponsive, try fully closing it and reopening it after you ensure Bluetooth is active.
5. If nothing changes, consider uninstalling and reinstalling the app and then logging in again.

Could you let me know if you've tried any of these steps? If so, which ones? That way, I can help you further with more targeted solutions.
