is it a bug or a “feature” that it is impossible to set a birthday - in my case to 1934.
I added the new property “birthday” in the concat page and clicked on the calender icon, select year, month and day and when clicked on the “OK” button alway the current year is set.
This is a know issue, which was planned to be resolved by an update by the end of this week. Should be released the coming week then, I guess.
There is a workaround as well. Perform an additional step and define day and month in one step and the year in a second step. To do that select the year with the year picker and directly hit the OK button.
