Unusable
This app and the corresponding website need serious improvement. Registering a payment option was not possible for me due to repeated “connection errors” while internet was definitely available, so the error message wasn’t helpful at all. Editing or removing payment methods through the app is not possible. The website is not optimised for mobile browsers and and therefore partly unusable on smartphones. A direct debit payment option set up on the website didn’t show up on the app. On a final note, the user interface is not optimised for large screen iPhones with FaceID.
