Why won't my product images load on mobile in portrait mode?

Every once in a while - it seems when publishing a new product - we get issues with product page images loading on mobile. We use the Archetype Motion theme. This product was just published and it will not load the product images. Just get a white loading bar and then grey that covers the entire upper image area.

This replicates in portrait viewing on iOS Safari, iOS Brave, and MacOS Brave during Inspect viewing mobile size.

If I rotate to horizontal mobile viewing it works fine. I can’t seem to locate why this is the case.

Yet I’m using the same product template here and it works just fine.

At a loss. If I switch to another product template, it will work just fine but I’m getting tired of having to duplicate product templates to fix seemingly bizarre problems. Love any help you might provide.
