I don’t like Isotope, but can’t get regular Tiled Mosaics to work

Hi,

Isotope is great, but it’s also incredibly awkward to use when I want to insert galleries into posts such as game reviews (and I really don’t want the headache of having to explain to all of my writing staff how to use it along with writing a detailed tutorial for them).

I would much rather use the standard Tiled Mosaic galleries that come with Jetpack. Unfortunately, I can’t seem to get them to work. I’ve tried disabling isotope and enabling Tiled Mosaics, but still the option does not appear when go into a post and go to add media – create gallery.

As a result, every single gallery in my imported content is now completely broken and not displaying correctly.

Any ideas?
