Bundled plugins offer the same core features and functionality as the standalone version of the item on CodeCanyon.
Some plugins may ask for a purchase code for registration/activation once installed, however, you can simply ignore these messages as bundled plugins do not require activation or registration. The plugin will still work as intended with the theme once the theme has been activated/registered.
When a plugin is updated, we will include the latest version of the bundled plugin with our next theme update. So you can easily update the bundled plugin when you next update your theme.
It is worth noting that we will fully test plugins to make certain there are no conflicts with our own update.
