I want to enter a timespan from 31.12.2018 to 1.1.2019 on the iPhone. After entering the start date the app prefills 31.12.2018 also as end date. I want to change the day from 31 to 1, but the app always changes it back to 31.
So I try to change the month from 12 to 1. Again, the app reverts it back to 12.
Me: Oh, you try to be clever and disallow the end date to be for the start date.
So I first change the year, then the month and than the day and everybody works.
