won't let me purchase sample i've been reading on my iPad
I click the BUY button, it asks for my Apple ID, the little circle begins for a few seconds and then it stops.
I tried it several times and the same thing happens.
And now the sample has disappeared from my book shelf.
I use the Canadian iBook store.
I was trying to purchase James Elmore "Perfidia"
Maybe I'm in the wrong group because there is no button below of iPad, however, there is one for my MacBook Air.
MacBook Air, iOS 7.0.4
