The introduction of the “official new app“ is in German, but the screenshots are in English, so I thought that @MrsGuin had merely provided the URL for the German language version of the app when posting this deal…
I changed the country URL from Austria (AT) to Germany (DE), Switzerland (CH), Netherlands (NL), Italy (IT), etc. and see that the app is widely available in Europe; however, when I try to open it via the iTunes Store, I receive the error message that this app is not available in my country (USA)… ☹️
