An App Store Updates Bug
It seems the App Store has a bug, something that I noticed first when I went to download an update to Daylite and then to Instacast. Neither of the apps was showing in Updates, even though an update had been released. And when I searched for the apps, both merely showed an “Open” button on their cards. However, tapping the card to review the listing revealed an “Update” button.
This doesn’t happen with every update, fortunately. Perhaps automatic downloading of updates will work around this, but users (like me) who have that setting disabled will have to rely upon other means to be notified of updates until this is fixed.
