Sleep and health metrics not working since update

[Anjou362]

Charge 4 automatically updated on April 29.  Since then, all sleep data and all health metrics have completely stopped working. How can this be fixed?

It’s good to see you in the community, @Anjou362.

Thanks for the details shared in your post. I recommend checking if your Fitbit device is updated to the latest version as updates come with new features and bug fixes: How do I update my Fitbit device?

Please also try the following:

1. Log out from the Fitbit app.
2. Clear your iPhone cache: How to Clear Your Browser's Cache on an iPhone.
3. Force quit the Fitbit app.
4. Reboot your phone.
5. Open the Fitbit app and log back in to your account.

By the way, I've moved your post to the iOS App board so we can keep our forums organized.

Hope this helps!
