Hi! I can't start career mode, it only says that it will be available after installation complete. But it is installed! What do i miss I play in Ps4
Check again if it truly is installed. Go to Notifications on your console, press Options and then Downloads. Many games first install a portion of it so you can start playing at least one or two modes. I am not 100 % sure this game does this as well but the message suggests so.
