Version 8.0 of the app, released on July 21 2025, introduces a new security feature. When the app is closed, it will prompt you to log in again.

The app is closed when

1. You click and drag the window upwards (swipe up).
2. When you restart your phone.
3. When your device closes unused apps, for example, to save battery life.

If the app is not closed, you will not be prompted to log in again.
