Apple Pay on Mac - can't add cards
When I first set up this new 2018 Air, I entered my cards on the Mac for Apple Pay. When I tried to use it, I find the cards weren't saved, so I need to enter them again.
When I try to add cards, I get the message "disable automatic login". When I go to Security and Privacy, I have Require Password enabled, but Disable Automatic Login is greyed out and I can't choose it.
Thanks.
MacBook Air (2018 or later)
