When adding a Done button to the keyboard toolbar the toolbar presents and operates as expected on the first view. If you present multiple views using .sheet() once on top of the other, with each keyboard using the same toolbar and Done button, when you get to the third view that has been presented, the toolbar disappears.
I have tried adding a FocusState, FocusValue, NavigationStack and NavigationView, I have tried making sure the field state is cleared and contained within every view but nothing seems to work.
