Appstore update Error.
see , I have three updates . But The Update button is vanished. I tried restating my phone, but not working. Update button shows for a millisecond time, and it's gone.
iPhone 5s, iOS 8.2
Others including myself are having the same issue. See Apps will not update
Which almost certainly means that it's an App Store issue which will have to be resolved by Apple.
