Update counter show 2 but nothing to update
My iPad Air 2 > App Store icon shows 2 updates > tab on it > tab on Updates (bottom of the screen) > The two app are Dropbox and a magazine > but both show OPEN and update all is greyed out > try to tab on the OPEN button for each does not help to remove the update counter
On my iMac > iTunes has no new updates > try to sync but not resolve
Reboot my iPad > fail to remove the update counter
What could be the likely problem for this? Thanks.
iPad Air 2 WiFi, Cellular, iOS 8.1.2
