Elementor, compatible with Classic Editor?

Hi,
I am considering using Elementor together with the Classic Editor. I plan to use Elementor as a page builder and the Classic Editor as a post editor. What issues might arise from using them together?

I saw the following content at the link below: https://wordpress.org/support/topic/edit-elementor-page-classic-editor/

“If you prefer to use the ‘classic editor plugin’ that disables the Gutenberg editor, it’s a bit more problematic although in theory it should also be compatible.”
