You can set your default city in your Settings page to make your map view always start there.
To get to your Settings page, click the menu in the top right & choose Settings. ‘Default City’ is in the list of options on the left.
I have a city listed as my default city, but it is not my city. How do I add my city as my default city?
I also have a Street listed that does not match the activity I have. I’m not sure how that street was entered. The only thing I’ve done thus far is to import one activity.
