Got my new Apple watch series 5 two weeks ago. went for my regular run of 4.5 km, and the watch showed only 2.7 km.
Also pace and other measurements were off by the same reason I believe.
Is there something I could do in order to fix it, or is it a hardware problem?
My iPhone X was on my, and I also tracked this run on a different android device and tracked 4.5 km, as the runway suggests.
