I'm a first time Kindler, so today I bought my first book. I had WN on and 4 bars. I waited 15 minutes and the book never showed up. Money was charged to my account and approved. I called Tech. Support for assistance. The Tech Support person had me do a few maneuvers and a reset. With that the book I bought appeared. He told me sometimes the transmission gets hung up somewhere and takes longer to transmit. Has anyone had this problem with K1 or K2? Just curious since the CS person, before transferring me to the Tech. Support, kept telling me I could download the book from "Manage My Kindle." I told him I was aware of this, but I wanted to make sure my WN feature was working properly, since it was the first time I was trying it.
