Simply the worst
The App is simply the worst banking app I’ve ever used. Every week they are updating the app and every week I simply even can’t login in. There is always a mistake in the App or my Konto is not available or “your action could not be completed”. And the best advice which App is giving you - “Try again later”. Moreover the Bank never inform you about the issues. You just can’t get inside your own account. And you have no idea when it will again work. Bad. Very bad.
