Amp Slide Cart Upsell Drawer

I like the app, and the team was helpful with any changes required. However, we could not make it work. When the cart has two items with the same variant ID (which is the case of file uploads or any line item - we use upload kit), the quantity buttons will malfunction, not being able to modify quantities correctly. I took the time to check this with the upload kit developer and sent Slide Cart support their finding for a fix. Sadly, I never heard back, so I ended up uninstalling.
