Images don't display on mobile

I’m having issues with my custom lightboxes on mobile. When a thumbnail is clicked, it sets off an interaction to make the image lightbox and the lightbox image displays go to flex and block, and the lightbox slides into place. My lightbox image is set to 100VW, and Auto height, so that it will be as large as possible. With height set to auto, images are apparently being rendered with 0 height. This issue only makes itself apparent when viewing on a phone, or in the phone dev mode, on standard desktop, it works fine. Any idea what is happening here?

I did find this thread where someone had a similar issue… This was caused by fixed taking the div out of the normal flow. I’ve tried wrapping all of my LB elements in another div and making them relative to it, but no luck.
