lately i noticed a deviation in barometer reading by 100 to 200 meter.. tried to calibrate manually and using GPS but every time after calibration the wrong reading back again.. also tried to factory reset the watch but i got the same result.. the problem is that the deviation is not fixed and this swing causes a wrong reading for floors...currently my watch SW version is 17.04 and sensor version is 27.16.. so is there any way to get back to former version to restore the normal barometer reading?
