I have seen API response can't be analysed by its own demo javascript. (some AU address case)So it must be an API response change.But there isn't any change stated anywhere.Try to test if its broken for you in a test case at below link,https://developers.google.com/maps/documentation/javascript/examples/places-autocomplete-addressform

To be honest, I was quite surprised it is "Paid App".
