Passcodes and Braille screen input

I have read on this site that it is possible to type in a passcode with Braille screen input, but it isn't working for me. It doesn't unlock my phone and I have to either shut it off and try touch ID again, or get out of BSI. My phone is an 8+.

Not working for me either

I have an 11, and for the past couple of months, using Braille in password fields or to unlock my phone has not been working. It had worked before. I'd love any help here.

It Doesn't Work For Me Either

I've never got BSI to work when typing in passwords. Do I need to use computer braille or something? Any advice would be appreciated.
