On my wife's iPhone 6 plus in the app store it shows the number 4 updates but there are no updates showing. It just shows the app updates that have already been updated.The update all is greyed out. I did a hard reset holding down the on/off button and the home screen button but it still shows "4" updates. How can I get that "red 4" off the screen? There are no new updates showing on the screen. Thanks for a reply.
