Update Failed: Download failed. Unauthorized
Update Failed: Download failed. Unauthorized You will see this error when you try to update to the latest version of the plugin but your license hasn't been activated yet.
Unfortunately, up and until v9.0, the plugin didn't try to activate the license key automatically. Instead you need to do this manually. Starting with v9.1 the plugin has been enhanced and it will try to activate the license automatically when entered in the designated field WP Admin > WPO365 > Downloads > License key.
Please watch this short video to https://youtu.be/WJQUw8xXtaI for instructions on how to obtain your license key and how to manually activate it.
