Well, I have fixed the issue with disabling lazy loading in Bricks and using Breeze plugin and native lazy loading images so I have no site to reference to now. But I will replicate the site on other server disabling the fix and give you admin access to it so you can investigate also issues related to slow performance on complex pages (related to this), because I still experience serious lag in specific cases with flexible content and very complex pages.
But it will take me a while because my hosting provider doesn’t have easy way to duplicate site. (need to export and reupload everything)
