Charge 3 stopped tracking sleep stages

I have an IPhone 8 and I did download the latest update yesterday.. Last night my Charge 3 did not track my sleep. I rebooted my Charge 3 and rebooted my iPhone as well. Still not working.

Hi there @Cindyatmb64, welcome to the Community Forums. Thanks for the details provided about your sleep data and for taking the time to troubleshoot it prior to contacting us. 

As a first approach, I'd like you to perform the following steps below for this situation:

• Switch the Heart Rate settings from On to Off and manually sync your Charge 3. To switch the heart rate settings on your Charge 3, from the main screen of your Charge 3, swipe left until you see "Settings", next swipe up until you see "Heart Rate" and switch it to Off.
• Once it's done, manually sync your Charge 3. To do so, open the Fitbit app, tap on the Account icon, tap on your Charge 3's image and tap on "Sync Now" 
• Next, switch it from Off to On and manually sync your Charge 3 once again. 
• Once it's done, restart your Charge 3 once again. To do so, press and hold the left button for 8 seconds while it is plugged into the charging cable as if it were charging. 
• Next, confirm that your tracker is snug on your wrist (the lights shouldn't be visible) We also recommend when you're not exercising, wear the tracker just above the wrist bone.

If after resetting your heart rate, you still don't receive sleep stages, I recommend considering the following:

• If you slept in a position that prevented your device from getting a consistent heart-rate reading or wore it too loosely. For best results, wear your device higher on your wrist (about 2-3 finger widths above your wrist bone). The band should feel secure but not too tight.
• If you used the Begin Sleep Now option in the Fitbit app (instead of simply wearing your device to bed). For more information on automatic sleep tracking, see How do I track my sleep?
• If you slept for less than 3 hours.
• If your device’s battery is critically low.

Give this a go and let me know the outcome, I'll be around.

Hello, mine has also stopped tracking sleep-it stopped the same day as your last update (2/6).  Perhaps there is a bug that needs to be fixed? I find this highly coincidental...,

Hi there @Sully65, welcome on board. Thanks for bringing this to my attention. 

If you're experiencing exactly the same, please follow the recommendations I've provided here. Additionally, please also try the steps below:

• Log out of your Fitbit app
• Force quit the app
• Turn off the Bluetooth
• Shut off your phone and turn it on after 1-2 minutes
• Turn on the Bluetooth
• Log back into your Fitbit app

I'll be around, keep me posted.
