Codebook v3.1.6 (451) on iOS 9.3.5 on an iPhone 5
Possibly a screen bug?
After adding a field to an entry, and returning to the entry while still in edit mode, the vertical line between the field name and the row-movement button (? … the 3 horizontal lines on the right of the display) is missing.
In the screenshot below, I added a field (‘Country’), then ‘Save’ the entry, then ‘Edit’ and added a new field (‘Gender’), to show the problem:
It remains missing until I tap ‘Save’ then ‘Edit’ again.
