Hi - can someone help with this issue? I’ve updated the image on the image banner on the homepage. The image looks updated in the customization preview but doesn’t update when you go to the site on desktop. It is, however, updated on mobile. Here’s my shop for reference: be-tween-2751.myshopify.com
Hi @be_tween 
Check the Theme customizer options to see if it allows to set image for desktop and mobile. Switch between desktop and mobile views to make sure the image is set on both screens.
