I seem to be having an issue with callback after logging into Google / giving access to to my account. Once logged in the redirected page is blank with no errors. The redirect / callback urls where added into the Google API app as per instructions provided in this plugin.Secondly I can\'t upgrade the plugin, when upgrading the XHR request from the admin 404s and redownloading the plugin from the link sent after purchase does not provide me with the latest version
