Hi!
I don't find a solution to let the weather widget show any other location than that of the first start of the edge.
I bought mine in a bike shop and set it up in the train back home.
Im using Connect on iOS, location services are enabled and allowed.
In Connect, I tried to disable and reenable the weather service. I did the same with the weather widget. No matter what I do, it is always showing the location where I first "used" the edge.
