I uploaded a while ago iPhone5 and iPhone4 respectively 640x1136 and 640x960 sizes. But size does not match in iPhone5 device. it displays 640x960 (iPhone4) size at the device.
I think, the iphone5 device cannot find 640x1136 size(iPhone5) because of unknown problem
Do you know why? The urgent problem.
Are you sure you published the iPhone 5 folio in Folio Producer? Are you sure everything is correctly marked so they are renditions of everything? Make sure the folio name and product ID match for all four of those folios in Folio Producer (see Digital Publishing Suite Help | Creating folio renditions for more information).
