Hi there, @Quinney84. Thanks for stopping by in the Community Forums. Thanks for trying to troubleshoot the issue with your Charge 3 before reaching out. 

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.

Hope that helps.
