I upgraded my old fitbit watch to a Sence big mistake. It shows me climbing 118 flights of stairs or even some days 200. It doesn't show my sleep pattern properly. I reached put for help with this matter & they say you haven't updated your app. I have updated it several times. Still same issues. There was one time, I was told to update because it showed in their system it wasn't updated. While still on the phone with them, I went to the app store & there was no update showing. Not happy
