Why won’t iPad generate new passwords

I’ve had 1Password on my iPad, Mac and iPhone for years. All the sudden, I can’t generate or change passwords in the iPad app. It’s either user error or a problem with the app. I’m using 8 and the latest rev. When I create or try to change a password, nothing happens. I can edit an existing password, but the password generator seems to have gone south. Hope someone can help. Thanks.
