iPad troubleshooting

Hi, folks. I had some Safari compatibility issues on a page I’m working on, and while I fixed them, I noticed something strange in Responsive Design Mode. Everything loads fine on phones and desktops, but I got fetch errors on iPad. I can’t think of any reason why this would be. I don’t have an iPad, so I can’t check this out for myself, so I wonder if someone with an iPad wouldn’t mind going to https://see-the-curve.netlify.app and selecting a country to see if it loads? Note: State selection works just fine regardless of device.
Thanks for your help!
