On my 735xt I used to record correctly the intensity minutes, suddenly it stops recording the step counting and any intensity minute after a workout.
I reset the watch and started recording the steps and the intensity minutes after a workout but the intensity minutes started recording much more that real.
Today I ran 10 min and recorded a total of 31 min (8 moderate + 23 min intensive x2= 54 min). the watch is not recording correctly the total min.
Any idea how to fix this?
