Post block

Hi there,
I’m working on localhost rebuilding my website.
I’m using the post block as archive page for CPT.
In this situation I have 15 different CPT/post and I setup the block post to load 10 (as Number of Posts).
So I’ve 5 CPT remaining but I can’t have the Load more button working: If I click on that I have the color changing as I setup but nothing happens.
In your live demo when I click on the button I see the”waiting” circle and then the loaded post.
Here no result.
What can I do?
This is my second ticket for support in 3 days but no answer till now.
Please give support because on your doc nothing is written.
Thanks
Lio
