I'm doing some testing with Gravity Forms version 1.6.9 and WordPress 3.5-RC1. The upcoming version of WordPress replaces the old "Add/Insert" icons with an "Add Media" button. I don't see were the "Add Gravity Form" button has gone.
Am I missing something obvious or is this something that y'all will address in an update before WP 3.5 is released next week? If not I'm going to have to hold off updating the WP core on my client sites.
