The app keeps crashing. What can I do?

We are constantly improving our app and regularly release updates. To make sure that apps continue to work as usual, you should always keep your operating system up to date. For example, our app is currently available from Version 5.1 for Android and 9 for iOS. If the app still does not work, we recommend closing the app first and restarting it. Restarting the smartphone can also help to restore the function.
