Hi there, @LinziMoxham. Welcome to the Fitbit Community Forums. It's sad to hear that your Versa 2 is not tracking your heart rate accurately. I'll be glad to help you. 

Please try the following steps to reset your heart rate settings:

• 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 2. To do so, open the Fitbit app, tap on the Account icon, tap on your Versa 2'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 Versa 2 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.
