Just checked again and I can see it’s working. It shouldn’t automatically update unless you have your WP installation setup to do so? Or maybe your host has your WP install setup to auto update? I’m not sure.
What if we just rename the theme to “Ambition Pro” in the theme files? I can edit the files from FTP info you’ve already sent over, but I’ll need a WordPress login to double check in the admin. You can create a Temporary Administrator login by going to Users > Add New.
Just let me know. I’d be happy to take a look.
