Codebook v3.1.6 (451) on iOS 9.3.5 on an iPhone 5
This might be a bug.
I created a field named ‘Date Of Birth’ as a ‘date’ data type.
I create a new entry then add a new field of this type. I select my required date using the date-rollers, which is then pasted into the new field.
If I create another new entry, then add a new field with this same custom date type, the app again shows the date-rollers with the previously selected date but but the display at the top shows todays date:
If I tap ‘Done’, then today’s date is pasted - not the date that was shown on the date rollers.
To actually get that previous date, I have to move one of the rollers a bit so it updates the date display at the top of the selection screen, then move it back.
Suggest that the date display at top match the date-rollers on re-entry to the date selection screen.
Personally, I like that it remembers the previous date I had selected.
