In the FAQ, the following is missing from the "Ticket inspection with your mobile Pass" section:
I have a travel plan with multiple train connections. Due to the delay of the preceding train, I miss the scheduled connecting train. Do I have to delete the old connection and enter the new one? What should I do if the remaining time to change to the new train is too short to enter the new ticket? In the worst case, do I have to wait until the next day?
