I noticed that using a URL form to enter a field specified as a date.
When I click on the field it provides a calendar to select a data, which is good, but on the iPhone iOS 9.2.1 the top of the calendar was truncated precluding selection of a date early than this week.
It turned out we could also manually type into this field, however when I entered a dd value of 99
it was happy accepted. I should also note that the entry formate was different that the one species in air table for that date field.
Ideally, on the URL form we could only select from the calendar in such a way that the calendar actually was all visible, or if we had to enter a date manually, an appropriate numeric only keyboard would appear. Right now the calendar selection appears, then the keyboard appears , and pushes the calendar off the top of the screen, this is why it is truncated I think.
