On July 16, 2018, Google pricing plan went into effect for Maps, Routes, and Places. But don’t worry, they give each account an amount of $200 free each month, regular usage of this plugin falls under that amount so you don’t have to pay for any fee. All you need to do is just filling a billing account for reliably accessing to Google Cloud Maps Flatform.
Please go to https://cloud.google.com/maps-platform/ , click on “GET STARTED” ,
tick on Maps and Places, click on continue, select the project in which you create the API key for this plugin and follow the guide.
