Question Author
Have just discovered that they must change the questions at midnight!!
I'd first looked just prior to midnight and it said inside back cover. Have just logged into it again - and the question is changed to the back cover!!! Fortunately the answer had been given so I could select P&O Cruises without asking for it again!!
So - the moral of the story is - ask the question well before midnight or wait till after then you've got a long time before it changes again!!
