Versa 2 stopped working altogether

[Therooster]

This might be dumb, I’m in the Canadian army and I wear my Fitbit whenever I go away for training, I like it to track my sleep and the alarm doesn’t bother other people when I have to get up at crazy hours. 
My last bit of training I was in very cold conditions. After the first night, -20C, all the sensors stopped working, SPo2, HR, etc. I have already tried restarting the Fitbit and it still does not work. Is there any other way to do a reset on the versa 2, or is there a way I can get them to start working? Or is it just pooched?

Hi there, @Therooster. Welcome to the Community Forums. Thanks for trying to troubleshoot the issue with your Versa 2 before reaching out. 

I'd recommend following the steps below:

• 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.
• 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.

If the above doesn't work, the best way to get help for this problem is to chat with us online or give us a call. Click here to get connected.

As a friendly reminder, please take into consideration the Versa 2's environmental conditions:

• Operating temperature

(-10° to 45° C)

• Non-operating temperature
