Upcart—Cart Drawer Cart Upsell

Klaviyo users beware - please reconsider using this app if you also use Klaviyo for your abandoned cart emails. Once you install this app, Klaivyo will no longer be able to see the scripts for adding to cart. It took us weeks to work out what the issue was (and thousands lost in revenue) before we worked out it was this app. When I contacted support about the issue, they actually knew about the issue but they don't let you know at install. I don't normally leave 1 star reviews but the coding on this app really impacted our store negatively. Support should offer to install this properly with custom coding for those customers using Klaviyo.
