I don’t know if this is the same issue or not, but it seems related. I just tried multiple times on my iPhone and iPad, both running 2023.8.0, to copy a password that requires MP verification. I entered my MP over and over, but never got it to copy. It would just return me to the screen where I needed the password, or would quit the Bitwarden app/extension entirely.
I’ve never seen this before, and it was deeply frustrating. I finally logged in via the browser and finally got my password.
