I have two Apple Watches linked to my Apple ID. Both are logged into iCloud and are showing in Find My.

System Settings on my MacBook Pro will not allow me to use Apple Watch to unlock the Mac, telling me that the watches must be logged into iCloud. Selection slider keeps bouncing back to off.

I have seen older threads on this issue and tried the fixes, but none have helped.
