Sooo if I scan the QR on the Start card, it takes me to a site that then opens up google play store in which googles tells me Item not found.. If I scan the QR on a printout it takes me to a Chinese site and tells me to download it, and anytime I do it does nothing, like nothing at all was downloaded...
