The trip summary is generated with information that we retrieve from your trip.
If the location we show as the furthest place from home is different from what you expected then we recommend looking at the location data that is set for the furthest step from home.
Go to the step -> tap 'Edit step' -> tap on the pen icon to open the location information for this step. Updating the location of this step should update the information in your Travel Book.
