Hello,
This is a slightly puzzling problem we’re having with a new client being on-boarded.
Essentially, we’re noticing an odd pattern as our client adds variant images to their products (primarily clothes).
When there are *few* variants, picking a color from the swatch will swap to the correct variant image immediately. If there are *many* colour variants, we need to pick both color and size for the switch to occur, and it seems like we need to have the variant images set for *every* variant of the same color. For the few variant products, assigning to just one of the sizes is fine.
I’ve included some links in the private content for reference.
