I installed Pandora on my Ipad 2 a few days ago. I set it down waiting for it to install, came back a few minutes later and the app was not there and had been deleted. When I try to reinstall it in the app store, it says it's already and installed but I don't have the app. I went on iTunes and it is checked as an app that is on my Ipad. I try dragging it and syncing it besides my other apps, but it didn't work either. I've not had this problem with any other app, any advice on how to fix this issue and get the app?
