@kotyarashop You are incorrect: the API with Google is completely free. This is declared in the plugin’s requirements and recommendations with a requirement for just a Google Billing account; no money is transacted.
Additionally, the steps needed to setup this plugin are very clearly shown within the plugin, most of these steps take seconds if they are followed properly and overall the process will take a few minutes, even for novices of WordPress.
Your review history is littered with impatience and stating things do not work with the absence of nuance in your approach. I strongly suggest you read the plugin’s requirements and recommendations before proceeding with further installs.
Then if you run into problems, at least make an attempt the view the forum and contact the author. In this case, you would have received a reply within minutes.
