From header missing in Mail on my MacBook Pro using Big Sur 11.7.10
My mail header "From" is missing. I've tried "View" to "Message" to "All Headers" and "Default headers". I have tried to slide headers. I can slide "Subject" and "Date Received", but cannot see "From". I have quit Mail and restarted. I've tried the "Help" search and can't find anything that works. How do I get it back?
MacBook Pro 17″, 10.13
