I've noticed this several times. When wanting to jump to somewhere else, I type in the place I want to go and it completely disregards what I just typed in. This time I keep typing in 'Peter 1' and then the box just reverts back to Zech 14, as if I didn't type anything.
If I can't use the address box to navigate to different books, I'm dead in the water. How do you even go anywhere without a steering wheel?
It's like it gets stuck and can't move until I close and reopen a new Bible tab. Then it works again.
