Versa 2 heart monitor stopped working

[Redsoxsluggr]

Hello, I have a Versa 2 and the heart monitor has stopped working (says “null” on my clock). I have tried cleaning it, resetting, turned on and off the heart rate (and syncing) and restarting it. Am I missing anything else? Just frustrating that I can’t monitor my heart rate when I exercise. Thank you for any help

Hi @Redsoxsluggr and warm welcome to the forums. 

I appreciate your message, and I'm sorry to hear that your Versa 2 heart rate monitor has stopped working. 
Thank you for your troubleshooting efforts. 

Could you please confirm if you tried the restarting as shown here ? 

If your Versa 2 is not tracking your heart rate data accurately you won't get heart rate readings. With that being said, 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 Fitbit device.
  
  To switch the heart rate settings on your Fitbit device, open the Settings app > Heart Rate > tap to turn the setting Off.  
• Once it's done, manually sync your Versa 2.
  To do so, from the Today tab, tap Devices > device image. Tap Sync Now. 
• Next, switch it from Off to On and manually sync your Fitbit device once again. 
• Once it's done, restart your Fitbit device once again. 
• Next, confirm that your watch is snug on your wrist (the lights shouldn't be visible) We also recommend when you're not exercising, wear the watch just above the wrist bone.
