Super bad for Seo

I used Elementor on about 40 pages. I got worried, since my pageinsights value for mobile was a constant 36. So I took the time and tedious work and reverted all pages with Block Editor and deleted Elementor. My pageinsights for mobile is now at 86 – 8 hours after deleting Elementor and not doing anything else than changing back to Block Editor.
The extra load of code it produces kills your SEO.
