The booking can easily be extended in the app.
In the case of an upcoming booking, the booking must be opened in the app. The start date and return date can then be easily adjusted under "Adjust booking time".
For an ongoing booking, the booking must also be called up via the app. The return date can then be adjusted under "Adjust booking time".
Please note that the booking period can only be adjusted if no other booking overlaps this booking period or the maximum booking duration is not exceeded.
