The answer to this question is yes; Ultimate Upsell can work with cart drawers. It does this automatically, all you have to do is set up the settings and conditions, and by default, Upsell will appear on your cart page. You may also use the “Manual Setup” option and copy the link of its snippet and paste it into any part of your website.
However, there is a catch - it may vary depending on the merchant's theme. Some themes may not be compatible with the app, which can cause issues with its functionality.
It's worth noting that even if the app is compatible with a particular theme, some adjustments may still be required to ensure seamless integration. In such cases, we may offer guidance and support to help you make the necessary changes.
