There are multiple conditions under which the banner will not display on your storefront.
Active dates: Check the Active dates setting. If the start date is in the future or the end date is in the past, the banner will not display on your storefront. Update the dates to display the banner.
Closed banner: 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.
Inactive discount: If the discount being promoted is inactive, the banner will not display. Update the discount to Active to display the banner.
Expired discount: If the discount being promoted is expired, the banner will not display unless there's a Default banner. Update the discount expiration date to display the banner.
If the Default banner is expected to show up, first verify that the default banner is enabled in the settings.
Seguno: Email Marketing users: If you are using our Seguno: Email Marketing app and you've opened an email sent from that app, then we will automatically hide announcement messages that request the visitor to enter their email address. Opening your website in a private browsing session in your browser should bring the banner back up for you.
Please contact Seguno Support if you continue to have issues.
