Ratings and reviews

So far so good! There was a misunderstanding of how the payments and UI works, but the support team was very prompt in explaining and fixing everything. Great job 👍🏼 Still -1 star cause the first line of the support team doesn't know how to deal with very polite and gentle feedback, but instead just arguing 🤦🏼

they have an English version, very easy to use. perfect for expats

One of the few apps that work really well in Germany :) the government and other providers should take this as an example!
