Great UI, disappearing purchases. Why are previously purchased titles, all on the same account, now showing as NOT purchased when they used to show as purchased? I read a lot, sometimes I forget titles and have inadvertently re-purchased books, this feels like a $1.5 trillion company cash grab from the little guy "maybe he won't ask for a refund..." and a waste of time, very un-lean. Simple prevention method: Bring back the "already purchased" button.
