Charge 3 stopped tracking floors

My Fitbit Charge 3 stopped tracking stairs about 1 week ago.  It's not even a month old. Please advise .

If you haven't already, try a restart (It doesn't delete anything) as labeled in the sidebar Restarting Charge 3, or follow these steps if you aren't around your charger.

1. From the Clock Face, go to the settings app. 
2. Scroll down to the About option.
3. Scroll all the way down to Reboot Device.
4. Scroll down, and click the checkmark.
5. Your device should have successfully rebooted if you see the clock face.

Hi there @MaddieGirl28, welcome to the Community Forums. Thanks for the details provided, we'll be glad to help.

Please restart your Charge 3 as my friend @SkullBurner has suggested. 

As you may know, Fitbit trackers that count floors have an altimeter sensor that can detect when you're going up or down in elevation. Your tracker registers one floor when you climb about ten feet at one time. It does not register floors when you go down. So I would like to take that into consideration at the moment to verify the amount of floors that your Fitbit has tracked. 

10 feet is an average between residential and commercial floor heights. If the floors you're climbing are shorter than 10 feet, you may find that the Fitbit tracker's floor count doesn't exactly match how many floors you've gone up. For example, if you climb 3 floors that are 8 feet tall (for a total gain of 24 feet), then the Fitbit tracker might only tell you 2 floors because it assumes that each floor is 10 feet tall and this is what happens to my at my granny's home. 

Another cause of inaccurate floors is moisture. Have you checked that already? For example, the pathway to the altimeter on the back of your tracker can become clogged temporarily with sweat.
