That's not the issue. The issue is the lack of account management in the Apple email app itself. For example, let's say you're using mail to manage a Gmail account and Outlook account. You can't simply manage those accounts from the email app. Odds are you don't have an Outlook login across multiple apps on an iPhone (fuck MS), so why can't you access it from the app itself?

Anyhow, this is becoming circular. I guess if you've used an iOS device forever you get used to its quirks, but it makes no damn sense if you use other OSes. Gmail, you can manage accounts within the app. Apple's app, you can't. Makes no sense.
