Sense 2 inaccurate heart rate during workouts

[Emmys8903]

My heart rate is inaccurately low during my workouts.  My charge 5 previously would have particular activities in the cardio range (130 or above).  While my sense 2 has me in the 80’s or 90’s doing the same activity.  I’m not sure why this is happening.

A warm welcome to the community @Emmys8903.

Thanks for sharing the inquiry regarding the situation with your Sense 2.

I recommend that you try restarting the device.

In addition, please follow the instructions in this article to improve the accuracy of heart rate information and check the information mentioned here about other factors that could affect your heart rate reading, this has been useful to other users who have experienced something similar.

I have tried ManuFitBit's suggestion and many others, and still have the same problem.  For more details, please see my post here, that FitBit has not yet responded to.
