Bought recently. Connected GPS to iPhone SE 2nd gen. Location always on. Distance of route that I’ve walked for years was slightly off from the beginning. But last two times out it is recording 4.85 or 4.9 miles for 4 mile route with corresponding ridiculously fast splits. Pretty sure that phone GPS is accurate enough. So where’s the problem here? Suggestions for fix? Will contact support. These massive errors aren’t acceptable.
