Versa 2 not tracking exercise automatically

[mgsilver]

For the past month fitbit will not automatically track any exercise, nothing. I get off my treadmill with 4000 steps and manually add the exercise and all of a sudden I have 2700 steps not 4000. I have tried everything. Treadmill and walking are on auto recognize. Weird how it used to but all of a sudden it won't and yes I have Uninstalled and reinstalled and shut down the fitbit itself.  Used to love my versa 2.

Welcome to the Fitbit Community, @mgsilver.

I am sorry to hear your Versa 2 is not tracking your exercise automatically. Thank you for trying to resolve this and providing the additional details. I totally understand how you are feeling and I am here to help. 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.

I recommend confirming that the Auto-Exercise Recognition setting is set to "On". 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 SmartTrack, please review our help article: How do I track exercise and activity with my Fitbit device?

If you're logging your activity manually, the manually logged activities override your device's data. For more information, see How do I manually log exercises in the Fitbit app?

By the way, I've moved your post to Other Versa Smartwatches board so we can keep our forums organized.

Let me know how it goes.
