Where can I find the license key for the bundled plugins
We bundle some of our products with other plugins like WPBakery Page Builder. For the bundled plugins you do not need the license key as the plugin will work great with our product even if you don't have any license key.
The license key is used to update the plugin and unlocks some exclusive features offered by the developer only if you purchase a license from them but the main features of the plugin will work even without the key.
