Versa 3 stopped tracking my heart rate, sleep data, and AZM data

[SunsetRunner]

I went to bed with 51% battery and woke up to my versa 3 in low battery zone. After charging the time corrected but now it doesn’t track my sleep nor will it track my heart rate meaning it will not break down my work out into fat burn etc. this is very disappointing. What should I do?

Hi there, @SunsetRunner. Thanks for the details provided in your post about the issue with your Versa 3. I understand where your concern is coming from. 

As a first approach, I'd recommend trying the following steps to make sure your heart rate is working:

• Switch the Heart Rate settings from On to Off and manually sync your watch. To switch the heart rate settings on your watch, from the main screen of your watch, 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 Versa. To do so, open the Fitbit app, tap on the Account icon, tap on your Versa's image and tap on "Sync Now" 
• Next, switch it from Off to On and manually sync your watch once again. 
• Once it's done, restart your watch once again. 
• 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.

Also, for more detailed information, see: What factors can affect my heart-rate reading on my Fitbit device?. Keep in mind that AZM are also calculated by your heart rate.

On the other hand, I recommend considering the following in order to get sleep stages:

• 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 with my Fitbit device?
• If you slept for less than 3 hours.
• If your device’s battery is critically low.

Hope this helps.

My issue is that I had received an email from the Fitbit after an extensive conversation twice once the representative was very rude the second representative was extremely knowledgeable and sent me to their technical side their technical side said it was beyond their scope so now they want me to get a different one and out of warranty this is because they only give you a limited warranty and even with what they offered it still cost a considerable amount of money considering if it's something beyond their scope why can't they reach out to other people that can pick up from where they left off that's my problem with Fitbit and other people and companies that do the same in different ways yay Fitbit don't give up when it's out of your scope can you reach out don't give up this is all the

I have the same issue. Since Friday my versa 3 no longer tracks sleep, nor does it log my stress Management Score.

The fix suggested is taken straight from help docs and does not remedy the issue.

Solutions like: Cleaning Fitbit, hard reboot, and uninstalling App also do not resolve it.

Can someone please respond with a useful and targeted suggestion. It appears to be a bug, not a user error.

Also, fix above for switching off heart rate could never work. See response from @MarreFitbit here on another post where they state versa 3 can not have heart rate turned off:
