STUDIO LIETZ review for Cartly Cart Drawer Cart Upsell
April 12, 2026
After some research the most straight-forward app with good design and customisation options. Unfortunately it messed with my cart and the whole site. Articles that were added / deleted didn't update, the entire page was slow and link reactions didn't work properly. When closing the slide cart underneath the so-far (theme) cart became visible. Customers were writing they almost hadn't purchased because the cart wasn't working correctly. So I had to delete it instantly. I wrote a message to the support team and if you manage to fix this I'd be happy to come back.
Thank you for your feedback—we’re really sorry for the experience you had. Please reinstall the app and reach out to our support team; our entire team (including developers and designers) is here to help you. We recommend keeping the app embed disabled initially to avoid it showing on your store. We’d love to fix this for you and have you back!
