Updating the name of a Location is performed within the Platform, which populates to the App.
- In the Platform, go to "Settings", then "Locations".
- Search for the Location by its current name (or store number), using the "Search" field in the top right of the page.
- Select the Location, then make the change to the "Name" field.
- Make sure to click "Save"
The name change will now propagate to the app.
