When you install the PRO version, the Joomla dashboard shows a message that a download key is missing.

You need this Download Key to enable automatic updates for our extensions. Our system checks that the key is valid and that your subscription is active.

You can find your personal Download Key on our website: 

https://www.joomill-extensions.com/account/downloadkey

Copy the Download Key and paste it into the Edit Update Site screen.

When you're done, press Save & Close.
