I have a Mini-2, with 64 Gig. I have IOs 8.3 I am trying to install Amazon music. When I went to App Store, the icon for this App, had 'get' by it. I clicked on it, it changed to a circle with a solid square inside it. in the northeast quarter, the line of the circle is thicker. In past, I remember the thick part was moving around the circle. I think this was showing that it was downloading. But now on this app, the symbol does not move. I have tried searching for the app again. I get message that I have bought app already. I then get a 'window' with some info about the App. It shows the same symbol, There is no way which I can find, to get the app to download. Any ideas.
