@constantine_ua are you sure you added al the different Google Maps API’s?
The one used to load the map is another one than the one to look up the address.
I switched them all on:
Google Maps Directions API
Google Maps Distance Matrix API
Google Maps Elevation API
Google Maps Geocoding API
Google Maps JavaScript API
Google Places API Web Service
Google Static Maps API
If you check your browser-console, I believe Google will give you an error stating which one is missing.
