Jetpack Slideshow not an option after upgrade for posts

I updated my WP and Jetpack Plug in. Now I can no longer make my galleries into a slideshow via a drop down menu option. I have spent hours troubleshooting. Have they taken this great slideshow away, am I the only one, is it a bug? I cannot promote my site now. It looks terrible as it has defaulted to tiled galleries with the file names. Advice welcome. Please see screenshot. My site is https://www.photocommunique.com I am using the Suits theme
