Uncaught ReferenceError: google is not defined

Problems when trying to use "Find address on Map". It seems the source for google isn't loaded.
This feature is used in combination with "Location" and "Profile2" modules.

Submodule: Location + Gmap 'Find Address' button

Uncaught ReferenceError: google is not defined

    at HTMLButtonElement.v.handle (jquery.min.js:5)

All location related modules and libraries indicate that the latest versions are used.
