Versa 2 not tracking my heart rate

[sdilni]

The last week or so, my Versa 2 was showing my HR at 108 bpm at all times of day, no matter what. I just restarted it and now it's showing my HR at 0 bpm. I've adjusted the strap, I've cleaned the back, I've synced it, my HR monitor is turned on. Nothing is working. What do I do?

Welcome to the forums @sdilni. 

Thank you for providing the details regarding your Versa 2 and for trying to fix it on your own. 

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 active minutes are also calculated by your heart rate.

Yeah...I found another question that had these steps. Tried them last night. No dice. 

What else?
