Item hide for already purchased items

I apologize for the late reply.

Restrict does not handle logging in itself but rather displays or hides the content based on various criteria. For example, if the content should be visible to logged in users only, then it relies on WordPress’ default user handling and it checks if the user has been logged in.More you can find here:https://restrict.io/restricted-content-documentation/restricting-the-content-of-page-or-post/
