Sorry for long time. We’ve just updated Conditional Logic to 1.6.4, which now supports Gutenberg. It works for
page_template and all rules internal for meta boxes / fields (such as show / hide a field based on another field). For some rules like checking by categories or custom taxonomies, there’s a limitation from Gutenberg that can’t be done at the moment. We’ll work with Gutenberg team to find a solution and will update the plugin as soon as we can.
