Hi, I am having the same on my portfolio page. https://www.feastaway.co.uk/recipes I emailed help and they said below. I have looked into re-sizing but the page is 4.6mb so less than the 5mb recommend and my 13 images are all 50-70kb each, less than the 500kb recommend.
The page never loads on mobile until you scroll down rigorously but it looks empty. I was looking at what other people use for portfolio pages in case there was a better way for me to display photos with links to info but I wonder if the same thing is impacting both.
I am interested in what this would do site-wide animation "slide"
I am going to go back to the help as I've shrunk as much a I can.
We understand that your "Recipes" page is appearing blank on a mobile device but is showing up on desktop. I've had a look at your site and I can see that when heading to the recipes page I'm able to see the content loading on both a desktop and a mobile device. I do see on the mobile device it does take an extra few seconds to load though. Since this is a Gallery Page and it has many images on it, this is likely the reason it takes a bit longer to load on mobile devices. I would recommend taking a look over this guide here that will provide some tips on how to keep your site mobile-friendly: https://support.squarespace.com/hc/en-us/articles/205815828-Tips-for-keeping-your-site-mobile-friendly Additionally, decreasing your image sizes so the page loads quicker may also help too.
