I wrote this note to clarify when I released version 1.3. If you have an old version of the plugin, you must login to your account and download both new plugins to replace the old PRO version.
For automattic updates
Version 1.3 of the Professional and Full Content add-ons have their own license keys, and the PRO license key is only used for upgrading subscriptions of bundled purchases on our website.
You must use your Professional license key in your Settings and click on the “Activate” button until it says “Activated”.
