Inspire 3 step count massively out

[MrStrick91]

I've had my Inspire 3 for just over 2 months now. Everything was working fine at first, but the past few days my step count is massively out. I already wore on my non-dominant hand but still had the app listed as wearing on my dominant hand. 

I WFH and I am in a good routine for how I get my steps, usually manage just over 10k a day

Examples of the difference in steps and also what my Google Fit app shows for the same time. I went for a lunchtime walk today and usually this is about 3km max. I got home around 13:50 and barely did any steps once I got in the house. How can it jump by nearly 2000 steps? You will also see that a little while later the step count has decreased by about 2000 again. 

One thing I have noticed is that eventually the steps do fall down back to what I would consider a usual level, but has anyone else experienced this and if so, how did you fix it? I've tried resetting my fitbit and logged out/in on the app but it's not done anything to solve the issue.

@MrStrick91 , A warm welcome to the Community! Thank  you for your message and screenshots. . 

  It seems that you might have MobileTrack on.

This feature uses the phone's sensors to count steps. This is for when you have left your Fitbit at home (e.g. while charging). Please make sure MobileTrack is not activated.
It may happen that the steps recorded with the cell phone overwrite those of the Sense 3  .

In the Fitbit app, tap the devices icon (top left corner).
There you will see the devices linked to your account.
If you see the Mobile Device Active option, tap it and remove it from the account.

If you are  having difficulties with the sync, please have a look at this: Why won't my Fitbit device sync?
