Hi Mike,
Actually, there aren't any change with Google Map function in OS Property side. But Google has just changed their policy, now, they don't allow us to use Google Map Application free anymore. You should register Google Map API and enter your billing information through this link.
developers.google.com/maps/documentation/javascript/get-api-key
After getting new API Key, you can enter it in OS Property Configuration.
Thus, the Google Map will work normally in OS Property system again
Thanks
