Hello, hope someone has a solution for this. I'm still in trial mode, and have most of my site done. Preview in web looks fine, but in mobile preview, those images are not mine, but generic images supplied by SS. I got rid of all of them in my build so how are these generic images still there? What am I missing? I uploaded a screenshot with an example image in mobile view. Why isn't it showing my images? Thank you!
