Weird charging situation after new firmware on Charge 6

[NewInNY]

Since my watch was updated to Firmware version: 66.20001.210.26 its acting weird when charging. I noticed this now for 1 week. Every time I charge the watch, it charges fine. When its finished charging or after I unplug it the spinning exercise is running. The active time usually shows a few mins after I connected it to the charger. 

It just did it again today. I have rebooted the watch and same issue. Now it throws off my exercise because it's adding the spinning when it syncs. 

anyone else getting this issue too?

Welcome back to the Fitbit Community, @NewInNY.

Thanks for informing me about this situation in regards to your Charge 6 charging changes after the firmware update. I appreciate you trying some steps to get this improved.

My best recommendation would be checking that smarttrack is off, you can check it following these steps:

1. Open the Exercise app.
2. Tap the Bike, Elliptical, Rowing, Run, Spinning, or Walk option.
3. Swipe up and turn off Auto Start. The next time your device detects this workout type, the Exercise app automatically will not open.

This should help you turn it off, you can check more information here if needed.

The device is not doing this during a workout. I am not wearing the watch, its connected to the charger. Its sitting on my desk charging when this issue happens. It started on day one after the firmware update.
