How do I edit a site location?

Open the project, choose the site location in the Site Locations box, click Edit, make your changes and click Update.

Steps

In the left menu, under Field Operations, click All Projects, then click the project's name.
On the Details tab, find the Site Locations box. If the project has more than one, pick the one you want from the drop-down list.
Click Edit. The Update Site Location page opens.
Change Site Location (the name, 2 to 50 characters), Location, Time Zone or Radius (300 to 1000 metres).
To move it, search an address in the box at the top-left of the map, drag the pin, or click the map.
Click Update. You'll see Site location updated successfully.

You can also edit from the Site Locations list, under Field Operations then Locations: click the row, or click ... and choose Edit.
You can't change which project a site location belongs to.
To delete a site location, click ... on its row in the Site Locations list, choose Delete, then confirm. A project's default site location can't be deleted, so its Delete option is greyed out.

Update is greyed out: make sure a location is set on the map.
No details found for this location: try another address, or click the spot on the map instead.
