Changing the default "from" email address when composing a new email in iOS 16.5
I have 5 different email addresses in Apple Mail (on iPad), all of them are IMAP except one old POP address. I have set my AppleID to be one of the new IMAP addresses and done everything possible to try to make the old POP address the lowest priority (it used to be my previous AppleID) and yet every time I start a new email (if I have "all inboxes" selected) it has the old POP email as the default "from" address rather than any of the IMAP ones set as a higher priority. iOS 16.5 doesn't seem to have a "set as default" option in settings anymore, what on earth do I need to do?
