iPad only showing unread emails
Hi, my ipad is only showing unread emails. As soon as I read them they vanish. I've read lots of things online about this but everything I try doesn't work. I've been in email settings and changed everything but nothing worked. The little circle at bottom of page with three lines just goes between "filtered by: " and "unread" neither displays read emails. Is it a fault with my ipad or is there a setting somewear I've missed. I can get them on my sons phone or by searching all mailboxes. But this is just so frustrating, please help me !!!!!
