I have purchased 1P 4 for iPad. When I view the iPad, all I see is the old 1P 3 icon. I've removed it from the iPad, reloaded it and it keeps coming back. On the iPad the App Store shows the 1P 3 icon, and when I search for 1P there, it shows the 1P 4 icon, but there's no download button. On the iMac which I sync to, iTunes shows the 1P 4 icon. I also have 1P 4 loaded on the iMac.
