Through the Nelio Content Settings you can delete a Nelio Content social profile and thus prevent new social messages from being scheduled or the ones you had prepared from being published. However, Nelio Content will still have access to that social network, as you may have other websites that do have that profile set up and, therefore, need to publish messages.
To completely remove Nelio Content permissions in Google My Business and ensure that none of your websites has access to publish in Google My Business, sign in to your Google account and select the Security settings option.
In the Security settings section, you’ll find third-party applications with access to your account.

Click the Manage third-party access option. In the next window you will see the list of applications that have access to your Google account and in that list, you will find Nelio Content.

Select the Nelio Content application and click the Remove access button.

From then on, Google withdraws the permissions to Nelio Content. Of course, you can always give Nelio Content permissions again by connecting the profile.
