Hi there, @Matt_Paradise. Welcome to the Fitbit Community Forums. Thanks for bringing this to my attention and for the troubleshooting steps you've tried. I'm sorry to hear that your Charge 5 is not working properly. I understand your concern, I will do my best to help you with this!
If the heart rate is not working properly, please try the following steps in the order listed:
- Switch the Heart Rate settings from On to Off and manually sync your watch. To switch the heart rate settings on your Charge 5, from the main screen of your Fitbit device, open the Settings app > Heart Rate > tap to turn the setting OFF.
- Once it's done, manually sync your Charge 5. To do so, open the Fitbit app, tap on the Account icon, tap on your Fitbit device's image and tap on "Sync Now"
- Next, switch it from Off to On and manually sync your Charge 5 once again.
- Once it's done, restart your Charge 5.
- 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.
