i can't get this function to work on my iPad. It comes up with the confirmation box but nothing happens when I press the mark read button.
Are you sure they are now now read? If the thread titles are bold it means they are unread. If the titles are not bold, they are all read.
How strange. It works now. But I swear to you it didn't earlier! Anyway sorry Rob for wasting your time. Must've been a glitch.
