Akshay_0157 , via OnePlus 8 , May 1, 2021 : Hello, Its been couple of weeks now I am using OnePlus band. It was working fine for me till latest update rolled out through OnePlus health app. Update has messed up heart rate tracking and free style workout tracking (which I used most of time). Heart rate tracking shows blank or doesn't track at all or mistrack completely. During workout tracking it goes completely blank for heart rate. As well as workout time is also showing wrong. Please check and fix this as soon as possible.
