Add Theme Support Jetpack Tiled Galleries

I’ve been using this bootstrap theme https://320press.com/wpbs/ as a starting point for some of the sites I’ve been building, but Jetpack’s Tiled Galleries don’t appear to be compatible.

I tried it with just a clean install, with no other plugins or hacks, and it still doesn’t work. I also uploded the “cleaner gallery” plugin discussed on other threads and that didn’t work.

Specifically, when the Tiled Gallery is activated, there is no option under Media Settings to display all pics in a mosaic. And, when I create a gallery in a post, there is no “type” field where I should be able to select tiles. It’s as if the plugin isn’t active at all.

Is it possible that there is something missing in the theme that would make Tiled Galleries work? Is it a conflict with bootstrap? If so, does anyone know how I could add theme support?

I’m thinking that, because the option doesn’t even show in the dashboard when I create a gallery, it may be something beyond just the theme. Any thoughts?

Thank you!
