A brand publishes its logo to a store, never its banner

A brand carrying both a Logo and a Banner sent the Banner to Shopify. It also changed on its own: a brand with only a Logo published that, and the day you added a Banner the next push quietly swapped the storefront's image for it.

A brand now sends its Logo and a category its Thumbnail, on every channel, with the Banner as the fallback. BigCommerce, which sent no image at all, sends them too.
