One annoyance that I find with iOS emal client is that it is only loading new emails when I get into the app. Since this process is not instant, sometimes I'm in the middle of deleting an email when a slew of new emails showed up. This can result in me deleting unsuspecting new email. Really annoying. But how do I undo it? I look at older iOS version videos where you can shake to undo it. But without shake to undo, what should I do?
