Developer options are enabled. When attempting to toggle OEM Unlocking on, the system requests my numeric password (fingerprint not requested) and I am returned to the toggle, which is off. When I attempt to toggle it on, again my numeric password is required-ad infinitum, with no ability to move the toggle. Apparent bug.
UPDATE: I tried disabling developer options and then re-enabling developer options a few times with the necessitated restarts. I was then finally able to toggle OEM Unlocking on, after accepting the warning notification. Hopefully this will solve this obvious bug which I am sure others encounter. Thanks for your interest and reply.
