Charge 5 and Fitbit app heart rate discrepancy

[LeslieFok]

I did some exercise, I saw on my device that I hit max heart rate over 140.  However, when I check the Fitbit app on my phone later, the max heart rate was only 128.  Please fix this.  I know the device was correct because I could feel my heart pumping.
