The sticky bar is not showing
Checks to run when the sticky bar or the cart bar does not appear on your store.
Most of the time the bar is hidden on purpose: the embed is off, a display rule excludes the page, or your theme's own sticky bar is on. Work down this list.
1. The app embed is on in your published theme
Open Online Store > Themes > Customize > App embeds on your live theme and check that Sticky and Quick Cart is on, then Save. The setup guide on the app's Home page shows a tick once it is. Switching it on in a draft theme does not change your live store.
2. Display rules allow the page
Open Settings > Display rules. Check that the page type (product, collection, home, cart, other) is on, and that product, collection, customer or market targeting does not exclude what you are testing. A rule limited to logged-in customers hides the bar from guests.
3. Your theme's own sticky bar
On Horizon and the themes built on it, our bar steps aside whenever the theme's own sticky add-to-cart bar is turned on. To use ours, open the theme editor, select the product information section and turn off Sticky add to cart bar, or set Design > Sticky add-to-cart bar > When your theme has its own sticky add-to-cart to Always show ours. Other themes with a sticky bar: with Automatic, ours hides while the theme's is on screen.
4. Scroll past the add-to-cart button
By default the bar appears only once your theme's add-to-cart button scrolls out of view. Choose Always Visible under Design > Sticky add-to-cart bar > Display Style to keep it on screen.
5. A drawer or pop-up is open
The bar hides while your theme's cart drawer, a cart popup or another pop-up window is open, and returns when it closes.
