This did'nt happen to me before. About 2 weeks since I sync my iPad and iPhone. I have 72 available app updates. When I click update all, A pop up message says updates were out of date and I need to refresh itunes. Now, where is the refresh icon on itunes? Anyone please tell me? I close itunes and open again when I could not find this refresh icon. But I can still see the 72 updates available.
