Charge 3 SmartTrack isn't working

[SunsetRunner]

I've been going on runs and working out and although I have added the automatic tracking, nothing gets tracked. On the previous Charge 3 I had it would start tracking the second I got on a bike, run, swim, etc why doesn't this one works like that?

It's great to see you here, @SunsetRunner.

SmartTrack recognizes activities based on the continuous movement of your arms. Sometimes, motions such as placing your arms on the bar of a treadmill, or pushing a stroller while you walk, may interrupt SmartTrack. Additionally, stopping in the middle of an exercise may interrupt the activity tracking.

By default, SmartTrack recognizes an exercise that lasts at least 15 minutes. If your activities aren't being recognized, lowering the time auto-exercise recognition setting to 10 minutes may help ensure they record properly.

For more information about how SmartTrack tracks activities, please review our help article: Which activities does my Fitbit device track automatically?.

Let me know the outcome. 🙂
