Hello,

Napoli theme includes bundled premium plugins such as The Grid, WP Bakery Page Builder, and Booked. These plugins are installed during the theme installation process. Some of these plugins may prompt you for entering a "license". 

You can ignore this license notice as bundled plugins do not come with an additional license. Due to Envato's licensing rules, we can only issue updates for these plugins when we issue a theme update 

Please continue reading below for further information on the process of how these updates are given.

Thank you,
Fox Themes Team
