Where do you receive your master key because everything doesnt show up in my mail?

If it’s not in your inbox, check your spam, junk, or trash boxes. If it’s not there in any of them, try searching for it in the “All Mailboxes” category. If it’s really not there, try to send the email again and check. Although if you don’t want to do this stuff you could just use a temporary key. Hoped this helped!
