Warning! You will lose the Block Editor in many places

This issue has already been mentioned here in this ticket. However, let me repeat that after activating this plugin, you will lose the Gutenberg editing feature on all post types except “post” and “page”.

I had the same issue and discovered the convert_to_blocks_default_post_types hook, where you can pass a list of post types the plugin should work on, which are the same post types where you will have Gutenberg. In my case, I simply added to my functions.php file:

add_filter( 'convert_to_blocks_default_post_types', fn( $types ) => [...$types, 'category-page'], 10 );

Otherwise, I see that in the next versions it will be an option that we can adjust from the admin panel.
