I did an FTP test on my friend’s PC (took advantage of his smart trainer), logged in as myself of course, and improved all my best times (5s/1min/5min/20min). The activity seems to have saved correctly, my total distance and meters climbed include that ride, my FTP has been updated, but my “your best” wattage show old values when I log in on my usual PC.
Is there a file I should transfer from his PC to mine?
