No integration and communication if your package is being delivered within Europe. I have a package on the way from Germany to Ireland and the only way to manage a delivery is to access their app which is only in German language or register an account on the website which will only accept German address. Once you register using an additional form because I am from Ireland, they will send me a link within a week to access my delivery. My package contains live aquarium plants and there is no update on the tracking after initial scanning 4 days ago. Please use UPS and avoid DHL if you want something delivered on time with the right tracking.
