Troubleshooting: Cart drawer not showing

This article is a draft and may be incomplete or change before publishing.

If the cart drawer isn't showing on your storefront, walk through these checks in order.

Diagnostic steps

Confirm the Oxify: Cart Upsell & Gift app embed is On in Themes → Customize → App embeds. (The Oxify: Product Upsell embed only powers product-page offers, not the drawer.)
Confirm you saved after toggling.
Check the right theme is published — not just edited as a draft. Oxify's own checks only look at your published theme.
Hard-refresh / open an incognito window to rule out cached files.
Check theme selectors if your theme is custom (see Custom theme selectors). In Oxify, open Home → Cart Drawer → Settings, click Show Advance Settings, and add the right selectors under Add to Cart Button Custom Query Selector and Open Cart Custom Query Selector.
In Oxify, open Home → Cart Drawer. If the embed is off on your published theme, an Oxify Cart Drawer is inactive banner appears with an Activate button. Click it, then Save in the theme editor.
On a brand-new install, make sure your cart settings have been saved: in the Cart Editor, make a change and click Save. The drawer doesn't load until cart settings have been saved once.
If the drawer opens from the cart icon but not after add to cart, open Settings in the Cart Editor and check that Open cart drawer on add to cart (under Other Settings) is on.

App embed enabled in a draft theme but production theme still has it off.
Save button not clicked after enabling the embed.
The wrong embed was turned on (Oxify: Product Upsell instead of Oxify: Cart Upsell & Gift).
Cart settings were never saved in Oxify.
Custom theme uses non-standard ATC selectors.
