In fact I can't even FIND those 'unread' emails that a specific mail account claims is there. I've tried setting all (the entire inbox) to 'unread' and then setting all of them back to 'read', but the account still reports some 'unread'. I don't want to trash the entire account and start fresh because there are important emails (lots of them) that I search for when I need them. But my iPads and my iPhone have each accumulated a number of 'missing" unread emails. I've posted this on Apple communities and they don't seem to be able to help (and now the new Apple security won't let me login anyway).
