Mobile responsive issue on iPhone.

I am not seeing every section load correctly or act correctly on mobile. In particular, all of the elements between the portfolio images and the footer are not acting right or loading to be seen. These elements are not showing up on my phone

I see them on the mobile view in the editor but they don’t show up properly on my phone. More specifically it wouldn’t load correctly on my iPhone 11 and my iPhone 6 Plus. Please check and help.
