I would like to remove the code from our shop (not only disable, but REMOVE) and have contacted the support last week, to help with removal. Until today, nobody bothered to reply!!! I remembered today because Shopify sent an email how the support went. The worst customer service ever, don't expect to hear from them if ever need them. 1 star for ignoring your customers!
I replied to your email a few hours after received it. I think you did not received my email. Please send to firstname.lastname@example.org, I'll reply back (Maybe you will get it this time).
About the code: It will be removed from your store if you remove it from the app. Or just uninstall the app.
