Vivoactive 3 heartrate sensor

My Vivoactive 3 heartrate sensor seems to be highly inaccurate during intense workouts all of a sudden??? How do i reset the sensor or is there anything i can do to fix this? I've had the watch a few months and it only recently has started showing a low heartrate (100bpm) during intense workouts where i know and can feel my heartrate is well over 150bpm. Please help???
