Unable to adjust the appearance on a purchased book
I recented purchased the new Barbara Kingsolver book, "Demon Copperhead". When my wife started to read it the font is too small and in a style that is hard to read. It can only be displayed as black on white. When we click on the Adjust Appearance icon the only choice that is offered is brightness. There is no selection of fonts or background tone, we can't adjust the size of the print. Since it is a bestseller I expected it to be a full-featured epub. Is there some way to unlock these adjustments?
This flaw appears in both Books for iOS and on the Mac.
