Hi,
In general, clone existing page is simple way to make exact same copy.
But new pages from scratch also you should be able to create as usual in elementor.
Please send us screenshot or video here to check exactly what is your trouble so we can help you: http://wpdirectorykit.com/contact.html

Hi,
So after communication with client we detected client have trouble with footer editing.
Right now you using standard wp footer, can be managed in widgets or wp customizer.
To manage it with Elementor, when editing a page you need to change the template to canvas.
Example:

We have some info about that here in docs: https://wpdirectorykit.com/documentation/#!/header_footer
We also prepared Video Guide for this: https://youtu.be/Lne68xokbwk
Let me know if this helps?
You are welcome!
