free version doesn`t work

I installed the free plugin in order to copy pages between sites in a multisite network. I receive the message that the page has been copied/updated but the page does not show up in the second site. I tried to copy both non pagebuilder created page and a rather complicated page created with Elementor.

What maight be the problem?
Thank you in advance!
