How to ensure location permissions are set to ensure an address can be set against a location.
When adding or changing the address associated with a location, the location permissions will need to be enabled in order to search on the address.
How to enable location permissions
To enable location permissions for this purpose, click on the location icon on the web browser as shown below.
This will bring up the option to 'Open preferences', click on this button to display these preferences.
Click on the lock icon, enter your password for your computer and check the 'Enable location services' checkbox. Then ensure the web browser, in this example, Chrome is checked to ensure location permissions are applied to this application.
Once enabled, the location icon as shown below will no longer appear with a red cross against this. The address will then populate with a list of more suitable options to select from and set against the location.
