That "My Location" feature in the Weather tab of the 9/20 build has been fantastic to use.
Before having it, when in small towns I would stuggle to find a local forecast, because even the famed "Weather Channel" on Cable TV would only provide forecast for a large city who knows how many miles away. The "My Location" feature has been giving me pinpoint results even when I don't know what city to lookup myself
. Just have to be sure your GPS is able to get a clear sky location lock, or the "My Location" feature will use your data connection's location.
