Can't find/use 1Password keyboard
I'm trying to use the password filling function on 1Password. The directions that are provided on you website say to go to the Settings app on my device then go to Language & Input. From there tap on Current Keyboard. My device doesn't have any category called Current Keyboard. I've clicked around and looked just about everywhere in the settings looking for the 1Password keyboard, but it is nowhere to be found. What should I do? Thanks for your help.
