Button not showing in post editor

Button to use the grid shortcode is no longer displaying in post editor. We moved the site to a multi-site environment, not sure if that is what would be causing the issue? We have the plugin updated but when you are on the post editor the button to use the shortcodes will not display. Also using tinymce advanced, so I deactivated it to see if that was the problem but did not help. Any help would be appreciated.
