The real problem is that the "Neighborhood" field is being auto populated with the city name and WU is not allowing it to be changed by the PWS owner. This has nothing at all to do with outdated maps or poor mapping accuracy. In my case, my location on the map is dead on. However, because the "Neighborhood" field is now auto populated and not editable, and the station name is the same as the "Neighborhood" field, everyone who adds a station in the same city as I am in, will have the exact same Station Name. I want to be able to distinguish my station from all other stations in the same city by having a station name that is unique.
In the new "My Devices" screen I can modify the "Name" field but that does not result in the "Neighborhood" field or station name changing. Before the update/migration, I was able to change the "Neighborhood" to what ever I desired, in my case I called it "Casa Loma" which is the name of my actual neighborhood.
