There are multiple conditions under which the banner will not display on your storefront. Please verify all of the following scenarios:
- Did you close the banner using the close button? The banner will not display again until you close and re-open a new tab or browser window.
- If the discount being promoted is expired, the banner will not display unless there's a Default banner.
- If the Default banner is expected to show up, first verify that the default banner is enabled in the settings. If it is of type Discount, verify that the discount specified is Active in Shopify.
If you still think it should be displaying, please open a support ticket and we'll take a look!
