I upgraded to iOS7 yesterday and today I can't find lots of my emails on the mail app. If I search in Inbox for an email from a particular person, it only brings up the last 5 mails from him, and I can't find any older ones. On the old mail app, I could choose "continue search on server" but that doesn't seem to be an option anymore. I urgently need some of these mails. Does anyone have a clue how to find them? Thank you so much!
