Update app button opening app instead of updating
Using a 5S on 7.0.4. I have multiple app updates available in the store but the "Update All" button in greyed out and when I click on any of the individual app "Update" buttons, instead of updating the app, the "Update" button launches that app instead. Never had this problem before and it just started in the last day or so. Tried closing all programs, rebooting and none of them are fixing the problem.
Any suggestions would be appreciated.
iPhone 5s, iOS 7.0.4
