Hi,
I have been using my FR255s for a year. The manual says that "Your watch displays heat and altitude corrected VO2 max. values when you are acclimating to high heat environments or high altitude."
I have heat and altitude acclimination pages on garmin connect however It never gets updated even if i have higher temperature and altitude workout periods.
The updates has not fixed it yet. Can you please help me to solve the issue.
