I can buy a new product/service from the Admin Center. In German, I select Abrechnung / Dienste kaufen and I get 3 categories with various products. Let's say, I would like to buy Project Online Essentials.
It's similar for all other products: I click on one product in the list and I reach a details page. This page has some issues.
Some texts, marked in the screenshot, such as users/month or the button Buy, are not translated. It should also be Abonnement-Optionen and the text Anzeigen dieses Produkts sound not very good - may be only Dieses Produkt. And the text Kostenlose Testversion is cutted.
