Keyboard not called when vim mode is in normal mode

What I’m trying to do

I’m using the editor in vim mode. On my iPhone it is essentially useless. When the editor, in vim mode, is in normal mode the keyboard is not called. I am unable to navigate in a note.

Things I have tried

On my iPad, when the editor,
operating in vim mode, is in normal mode, the keyboard is called. I can navigate in notes.

I don’t know what the situation was when I posted this. Very possibly absent mindedness. In any case, it is working just fine right now.
