Incorrect redirect on SoapUi Learn page

Hi guys. After entering Learn section on Smartbear’s SoapUI page (soapui.org/learn/), there’s an option to read The Beginner’s Guide to Using and Testing RESTful APIs. After clicking Read the ebook button, I am redirected to SmartBear staging environment instead of getting the ebook. is there a way to read it? Cheers
