Hello,
In the latest Elementor version, “Sections” have been replaced with the new Container element (Flexbox or Grid). That’s why you don’t see the option to create a Section manually anymore.
You need to enable the container to add something new. But, if you still want to use the old Section layout instead of Containers, you can re-enable it in Elementor -> Settings -> Features and set Flexbox Container to Inactive. After that, the “Add Section” option will appear again: https://prnt.sc/LdBegd22tJhW
However, please note that to use our theme dummy data, you will need to keep the Container option active, since the demos are built with the new Container system.
Best Regards,
