BTW, what happened to Outlook on iOS recently? Three months ago it was snappy, started immediately and notifications were cleared the moment messages were read; these days it takes ~5s to start, unread notifications stay for another ~5s after the message is read, confusing me about having new mail, and if the same mailbox is set up on two iOS devices, only one gets notifications. Is old Microsoft back?
