If you have purchased the Woo Essential plugin from Elegant Themes/Divi Marketplace, you don’t require a separate license key for any of the third-party plugins.
All you need to do is just activate the Divi Theme license, that would be enough for updating – from then on, you will get an update notification.
To activate using the Divi Theme License:
Please go to the Dashboard > Divi > Theme Options >
Updates – there you can activate the Divi Theme license.
Updates – there you can activate the Divi Theme license.
