I already use this website https://www.fitfiletools.com to fix timestamp. But still not working.
fit file
Hey there!
You should have an up to date fit file for each ride saved locally on your device (other than on Apple TV).
For more information on finding that file, check out this handy support article.
If you continue having this issue, please contact our Community Support team with your log files so we can investigate this with you further.
Ride On!
