Post / Page revisions

The Wordpress content revisions feature (WP_POST_REVISIONS) is not displaying for the default Post and Page types. It is working for a custom post type, though.

I tried deactivating all the plugins, changing the theme, and configuring add_post_type_support. Also, I didn’t see a reference to WP_POST_REVISIONS in the env config. Is there a setting that I’m missing?

Note: I’m using the full Roots stack.
