I seem unable to reach that page. When I log into iCloud Mail, I get the page shown in the attachment, which is useless. Nor can I find my way to the menu that you suggest from within Mail. Where am I going wrong ?
When I follow that link, I log into iCloud Mail, and I get to the page shown in the attachment below. Where do I go from there ? I do not want to waste your time, so I had best admit now that I am visually-impaired, so sometimes have difficulty in reading text, especially when it is rendered in the scheme beloved of website-designers of pale blue on white.
