I just bought the Vivoactive 4 and in my recent paddles I see ridiculous speeds (300,000mph). I reviewed the data from my Vivoactive HR and that is not showing the crazy mph.
Seems to a GPS issue but i paddled the same course and wore the GPS on my writs both times. I moved the Vivoactive 4 to a static position and it still showed the wild speed.
Anybody else having this issue?
Thanks
