I get very high HR during a cardio activity, firmware 2.40
Is it only me that have such problem ?
For example if you just walk and select cardio activity the HR is very high - 150-160 but actually your HR is 70-80 !!!
I played with tight/loose but no change at all.
If you select Run mode for example - HR is looking normal...
For me that is serious bug defenitely !
