Love the book, but I wish they would either fix or remove the share feature, because it is frustrating. It allows you to share maybe once, maybe twice, then you get weird error messages that make you think something is wrong with your phone. There is nothing wrong with your phone, they apparently just don't want you to share, so why not just remove this feature? I guess the app designer feels one way or two shares might generate a sale, but more might inhibit sales.
