Hello,
I’ve enabled Elementor for static blocks – https://prnt.sc/9XcvBLuCIq2Y , so you can edit Footer using Elementor now – https://prnt.sc/WWJ0sZJVcA7P and PreFooter https://prnt.sc/N0cGcKT-dkjN
Go to Theme Options > Speed Optimization > Menu Dropdown Ajax Loading, Menu Dropdown Cache, Menu Cache, Static Blocks Cache > Off. Activate mentioned options once all changes to the header/footer will be done.
Regards
