All your content from the Galleria Shopify App is delivered via CDN to ensure high availability and fast loading times from wherever customers access your site. It can take a minute or two for all the servers around the world to get the latest update and deliver the newest version. Just try reloading your site a couple of times and the newest version will show up.
TIP: If you are logged in as admin in your Shopify Backend while testing your shop this problem will not arise as we will fetch your content directly. Make sure the Shopify Admin Bar is visible while accessing your Shop.
