Hi, I have my Garmin FR 235 which stopped updating the VO2 max around 3 months ago. I got this watch new a year and half ago and i have been training without it in the past 3 months, because it does not matter what i do it does not get updated. I have seen and done some troubleshooting people have been recommending and still not working. What Garmin team is recommending for this? thanks
