IPad mail app does not show old emails – I can't mark them all as read I have started using my iPad again after long inactivity. The mail app shows 7,288 unread email. I would like to get rid of that red number, the problem is that the mail app does not load old email – and so I can't mark them as read. By the way, is there a way to mark ALL that 7,288 as read in one go?
Actually I found out that the problem was simply due to the fact that I had a lot of unread messages in the "social" and "promotion" folders on Gmail. Best way to get rid of all of those unread emails: do a search using the query is:unread on Gmail's web interface.
