Hi Tom,
Thanks for getting back to us quickly, I can access your Linkedin account now.
But it seems like after authorize the Linkedin user account from autoposting configuration page, I noticed it didn't pop up the Linkedin screen, check my screenshot below.
May i know which business page you would like to autopost to? Or you only want to autopost to your Linkedin profile page?
By the way, can i have your FTP access so I can troubleshoot on this issues if needed.
