I bought this cookbook not too long ago. Now I see a duplicate copy, identical in every respect, except that that copy had a revision dated in 2018, whereas my copy’s last revision date indicates it was done in 2015 - over three years earlier!! What gives?? I expect to have the latest revision provided automatically and NOT have to pay for the cookbook again, but that’s exactly what I would have to do in order to get the latest update. It makes me feel VERY leery about buying iBooks from here on out...if I cannot rely on Apple to keep this on the up and up. It’s truly a disturbing and disappointing discovery to say the least. Please fix things, Apple!
