From the new version (from 24.1) of DB Navigator, you will only see the mobile phone ticket for the currently valid month. The validity period on the mobile phone ticket is automatically updated at the change of month on the existing ticket. No additional ticket is displayed for the following month. The message "Tickets up to [date] are already on your device" means that the update for the new month will take place automatically on the first of the month. There may be a delay before the period is updated in the ticket preview under "Travel". Please open the ticket so that the QR code is visible. The current period is displayed on the ticket. This display is relevant for use and control.
