Why doesn't my pop-up offer appear when I add a product to the cart? (Essential Upsell app)

The pop-up appears at a different step depending on its placement:

• Product Page placement: the pop-up appears when the shopper clicks Add to cart.
• Cart Page placement: the pop-up appears when the shopper clicks Checkout in the cart or cart drawer. Adding a product alone does not open it.

If the pop-up still does not appear, check the following:

1. App embed. Go to Online Store → Themes → Customize → App embeds and make sure Essential Upsell is turned on for the published theme. Click Save.
2. Offer status. The funnel must be published, not only saved. It must be a pop-up offer, and its trigger must match the product you are testing.
3. Offer products. The offer products must be published, available, and not already in the cart. If every offer product is unavailable, the pop-up stays hidden on purpose.
4. Fresh page load. A pop-up triggers once per page load. If you tested the button earlier on the same page, reload the product page and try again.
5. Other pop-ups. Only one pop-up can use the same Add to cart click. Temporarily turn off other pop-up offers and product add-ons, then test again.
6. Required product options. If the product has a required personalisation, engraving, or other option that is not filled in, the app does not open the pop-up. Complete the required fields first, then click Add to cart.

For the placement and trigger settings, see the Essential Upsell pop-up setup guide.
